I have noticed that with the LAN expansion card inserted, my system boots extremely slow, the grub menu entries appear incrementally, reaction to key presses is very slow and the linux kernel does not get to the decryption screen within about 60 seconds.
If I remove the LAN expansion card, everything works as usual.
If I enable the BIOS network stack (I had it disabled because I thought I would not need it), it works fine as well.
So there seems to be some problem with the expansion card inserted and BIOS network stack disabled.
Can other people reproduce this problem?
Hi @John_Obscurant, which setting in the FW16 BIOS are you referring to Network Stack?
I do have a FW16 ETH card but not installed. Not high up my list but i will test when i have some time.
I have also noticed two more things:
-
boot time (from screen power on to HDD decryption password entry) is still slower (around 2x) if the Ethernet expansion card is connected and the BIOS network stack is enabled
-
most of the time, the Ethernet expansion card is not available as a device in the OS (Fedora Linux). The journal shows:

Mär 05 19:18:54 joshua kernel: usb usb1-port1: Cannot enable. Maybe the USB cable is bad?
I have to remove and re-insert the card once to make it available and connect to the network. The journal does not show removal, but re-insertion is correctly detected:
