Description Tamas Vincze 2012-08-24 13:34:18 UTC

After updating to kernel 3.5.2-3.fc17.x86_64 udevd crashes on boot causing the system to end up in a root shell.
With kernel 3.4.6-2.fc17.x86_64 udev works fine, but X fails to start because of an nvidia api version mismatch. So the last "yum update" rendered the system pretty much useless.

Version: udev-182-3.fc17.x86_64

Comment 1 brm 2012-08-31 14:58:57 UTC

I see the same fault.  I have an Intel D975XBX2 motherboard with ECC memory.

What is your setup?

Comment 2 Tamas Vincze 2012-08-31 15:06:56 UTC

Asus P5WDG2-WS mobo with ECC memory.

It may be a kernel bug, see: https://bugzilla.redhat.com/show_bug.cgi?id=848149

Comment 3 Harald Hoyer 2012-09-06 10:37:09 UTC

seems to be a bug in i82975x_edac
