Hello,
since the first version of 2.6.12-rc1 and mm[1-4] kernel I can't use any
of my PCI-Express devices that worked with all 2.6.11.[1-6] kernels. It's a real odd right now.
I have 25 computers with an Intel 925XE Chipset based motherboards and Intel 6xx CPU on it. So far it does not metter which vendor I choose (ASUS,ABIT,MSI etc.) the problem stay the same and spread all over.I
tried to boot with pci=routeicq but it did not help to get one device
working with any 2.6.12-rc1-xx kernel. As I mentioned before I tested it with on several (over 25 computer) with various motherboards (with ASUS,ABIT,MSI etc.) no luck. Its an 64bit system with [EMT64] and SMP/SMT and preempt enabled + cpufreq.
My first look was on PCI Routingtable and I found a difference to 2.6.11.x working kernel:
I've got the same problem with i915 on Asus P5GDC V Deluxe Mainboard.
This fragment of dmesg is from 2.6.12-rc1-mm4 kernel:
