After updating my dom0 kernel to kernel-latest (v6.12) , when I boot my computer the USB keyboard is completely unresponsive. The result is that I cannot enter the LUKS password to the decrypt the hard drive and continue the boot process. The keyboard works with GRUB. Since the computer does not have a PS/2 keyboard port (USB only), the only way to get out of that is to forcibly reset the system.
If I boot with an older kernel (6.11), the USB keyboard works and I can boot, so that’s what I have been doing. But I would like to know how to fix this before the older kernels get pushed out of my system.
Do you see any usb-related errors when booting 6.12? If you can’t switch to detailed view with ESC key, you can remove rhgb and quiet options from kernel params in grub.
Is there something special about your hardware? Is that an extra USB controller on a PCIe card, or the standard one built into CPU/chipset?
I am using an extra USB controller on a PCIe card (where only a known keyboard and mouse are plugged in), so I can keep that one in dom0, while all the other USB ports go to sys-usb.
I booted without the ‘rhgb’ and ‘quiet’ parameters in the kernel command line, but the lines go too fast, and the framebuffer still gets initialized so I lose access to the earlier messages (nothing about USB in the ones I can see, they are mostly related to the GPU). I tried taking a video of the boot, but it’s too blurry to read. I’ll keep trying to see if I can get those messages, but if you have any other ideas to try, I’d be grateful.
