I started experiencing this same issue. Weirdly, if I plug in a microphone in to one of the USB ports, the problem goes away. The second I unplug the microphone, the problem returns. Can you tell when I was unplugging and plugging the mic in? 
Please give this a try. I am not seeing this issue whatsoever with the recommended OEM kernel.
No a or b, just sudo apt-get install linux-oem-22.04 which will give you 5.17.0.1026.24-oem after reboot.
I can’t seem to write a long reply, I get a “403 forbidden error”.
Same error though with kernel 5.17.0.1026-oem: a kworker at nearly 100% CPU utilization.
Also firefox is unhappy: 130% CPU usage for no apparent reason. The Firefox Task Manager shows 130% for the Firefox process itself, not for any particular tab.
Let’s see if we can find out why I am unable to replicate this using the recommended linux-oem-22.04 kernel, fully up to date Ubuntu 22.04
-
Active applications (even if merely running as an indicator, GNOME extensions added, etc. Some software reacts oddly to USB devices being added.
-
All the latest updates have been run?
-
Is this happening with specific items added? USB microphone, storage devices, etc? If 3.5 mm mic jack, indicate this as well?
-
Please replicate this issue, then what is your output for (once run, arrow down, to see all the details):
journalctl --since "5 minutes ago"
I’d like to see those details from each of the affected. Using this time limiter should keep the details short and super relevant to the most recent event.
If I can determine the trigger, I may be able to confirm this is a kernel issue vs a device issue, then take appropriate action.
Easy to replicate, in ubuntu 22.04 updated to latest.
Active applications: even on a fresh reboot without any.
To activate the issue, load the xhci-pci module, which enables USB devices, including the camera.
In the bays, I have two empty and two full, with a USB-c and a USB-A.
$ date && sudo modprobe xhci-pci

I get “403” error when attempting to edit the above post. Wanted to add:
Headphones: the Framework laptop has a 3.5 mm jack, but I don’t have anything plugged ot it. As far as I know it makes no difference.
Gnome extensions: I don’t know that I’ve added any beyond those present in vanila Ubuntu 22.04.
Wayland vs Xorg: bug in both, but I use Xorg because of this other bug with Kazam an Wayland (can’t write video, only audio): Bug #1992360 “Kazam video screen capture generates empty or blac...” : Bugs : kazam package : Ubuntu
To activate the issue, load the xhci-pci module, which enables USB devices, including the camera. Or reboot.
In the bays, I have two empty and two full, with a USB-c and a USB-A.
The USB-A has given me trouble before, with a mouse that works for a while and then stops working, with “overcurrent condition” in the dmesg: USB port stopped working: over current condition - #10 by Cheese
That error with overcurrent happened before this kworker error ever showed up. I.e. prior Ubuntu linux kernels back then didn’t have a kworker at high CPU usage.
Thanks for the clear outline how to reproduce this. I have attempted to reproduce this on two separate Framework laptops (both 11th and 12th gen).
-
You’ve had this happen on 5.17.0.1026-oem and 5.17.0-1018-oem
-
You tried rebooting to the prior kernel
5.15.0-47and `5.15.0-46, but with the same result. -
You removed all USB-c expansion cards except for one with an USB-c pass through, to no avail.
-
This began happening starting on the 21st upon rebooting the framework laptop (which had not been rebooted for several weeks).
So if I have all the details correct:
-
Happened starting the night of the 21st after a reboot (it had not been rebooted in several weeks)
-
Multiple kernels have exhibited the same behavior as of the 21st.
-
Framework laptop worked fine before said reboot.
Next steps to take
-
Kernel version appears to be immaterial here, and we’re seeing additional issues that symptomatically feels like your install has gone south. (Firefox behavior, kworker). So bear this in mind as we take the next step.
-
Create and boot to a Live Ubuntu USB. I have not seen this tested in this thread. This is the absolute first stop when rebooting and update are not helping. If it works, you’re able to modprobe xhci-pci without it going nuts (as I experienced on two separate Framework laptops), then we have an indication as to what is wrong; the install went south.
-
If however, the behavior continues when you modprobe and Firefox is also going nuts, then we may be looking at a hardware issue.
Thanks, I will try out booting from a USB stick. Now I have to find a new USB stick and also time to test it …
By the way this is indeed an 11th gen intel i7:
$ cat /proc/cpuinfo | grep "model name"
model name : 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz
Appreciate that. Yes, please do try a live boot and let’s compare from that.
I’ve had this exact issue occur on a few different versions of Fedora.
For me it seems to most reliability occur when I’ve enabled the “Battery Disconnect” function in the BIOS menus.
Since yesterday night, when I opened up the laptop to take photos of the board and ports, that I don’t have this bug any more. I am beyond puzzled (and happy, yet fearing it will come back). The kernel is 5.15.0-58-generic which I had tried a few days ago and it had the bug; yesterday tests were done with 5.15.0-56-generic.
This week I will be plugging various USB and HDMI devices in the course of my work and we’ll see what happens then.
Delighted this has (be it mysteriously) resolved. 
Not resolved. So this morning I plugged the ethernet card, and a USB-A mouse. For a while, all good. But then BAM! The kworker is up again at 86% CPU or higher.
Would a dmesg help? Here are the last many lines. At the end, again, “overcurrent condition” related, most likely to the USB-A mouse, which stopped working.

Okay, so we have devices attached. I will match the devices attached (this time also adding the Ethernet expansion card to see if I can replicate this and call it a bug).
If I cannot, then we may have a hardware issue with either the expansion card or the board itself.
As I prepare an external USB pendrive to test the booting from it as you suggested: any linux OS you’d prefer? Ubuntu 22.04 LTS would do?
Is a good choice. Also Fedora 37.
Booting from a USB drive gives the same result: after plugging in the ethernet expansion card, the kworker jumps to ~90% CPU usage.
I’ve traced what the kworker is doing with:
# trace-cmd record -e workqueue:workqueue_queue_work
# trace-cmd report > trace.log
And these are the first 100 lines:

Only “solution” I know is sudo modprobe -r xhci-pci, but of course then the buiilt-in camera and the ethernet expansion card don’t work.
To confirm:
-
Booted to Live USB only, not booted to the hard drive.
-
Inserted Ethernet expansion card, CPU spike?
This is beginning to feel like a bad expansion card as it cannot replicate it here with a known to be good working card.
Try one more time, expansion card inserted powered off. Then boot to the Live USB, report back.
The same issue as described above, witnessed it by launching top and having kworked using one CPU, solved by removing the module, all the expansion cards, and reboot:
sudo modprobe -r xhci-pci- Remove all the expansion card
sudo modprobe xhci-pci- Put expansion card one by one
