Intel Hardware not recognized by udev

Hi,

after latest update, my machine wont recognize intel hardware.

lspci doesnt show i915 module loaded, ifconfig only shows "lo" interface, and lsmod also does not list i915.
lspci lists my vga (Xeon E3-1200) and ethernet (82579LM Gigabit), but lspci -v wont show a line like "Kernel driver in use" for these devices.

For some strange reason these modules dont get loaded. I have no idea left, already searched a lot but nothing helped.

Any ideas?

Ciao Stefan

Re: Intel Hardware not recognized by udev

I'll wager two credits that the kernel you are running is not the kernel that pacman installed.

Compare the output of uname -a and of pacman -Qi linux
Check the revision numbers?  Do they match?  If not, tell us about which bootloader you use, whether it is BIOS or UEFI, and the contents of /etc/fstab.

Re: Intel Hardware not recognized by udev

Thanks for your answer!

Uhm, I kinda "solved" the problem by downgrading to 3.16.3 which is now currently running. I expect 3.16.4 to be the active kernel before downgrade, but I didnt double check, but it was definitely the kernel package that was installed at that time.

How would it be possible to run a different kernel from the one that is installed? I do not understand. Should I upgrade again and check if this is the case?

It most often happens when you upgrade while /boot is not mounted. The old kernel image is still on the boot partition.

yeah, now i get it, that is most likely what happened! Definitely I didnt (yet) add /boot to fstab. My bad :-/

EDIT: removed downgraded packets from ignore list and everything is still working, thanks a lot. :-)
