I ordered my FW13 7840u at the end of December and received it the other day. While waiting for the laptop to acclimatize (winter), I came upon this thread. It upset me greatly as the machine my FW13 replaces has been having a similar DPC watchdog violation (though it is on boot, causing boot to hang). The machine being replaced is a Ryzen 5 3500 or something similar. It’s an Asus Vivobook.
I turned on my FW13 today and made note of something. I wonder if anyone has tried regressing their drivers back to the original installed version. While we don’t have the OEM driver (the date on first boot for the AMD driver is either 9/24 or 9/27), I wonder if rolling back to the last WHQL drivers from this time period (that’s 8/2 by my eye) would change anything? They are available under “Previous drivers” on AMD.
I have yet to get a BSOD with a few hours uptime on OEM and bundle drivers from the KB. I am installing 11/1 WHQL drivers from AMD now (driver only install) and will report back on stability after 5 days, I guess. I also installed GRC’s InControl to suspend feature updates in Windows 11 for the time being. In fact, I bypassed the online Windows setup and paused updates before configuring my WiFi. So as far as I know, there have been no Windows updates on my machine.
Edit: I have also not updated the BIOS although the unit seems to have shipped with 3.03.
