Subject: Further Sandybridge woes (including IRQ n: nobody cared, and video
crashes)
Like many other posters I have the dreaded IRQ nobody cared problem. But
whereas others have more complicated situations (e.g. multiple device
sharing an IRQ), mine is quite simple, and none of the workaround
suggestions I've seen work.
There are multiple symptoms which I include here as I don't know which
are related:
- System boots ok but IRQ Nobody Cared occurs on additional ethernet
board after about 15 minutes (main problem)
- Video is fine in character mode. X starts ok, some repaint hiccups,
but terminating X hangs system with loud continuous beep and need to
remove power (even reset doesn't work) if from runlevel 5, or with
several second hang followed by reboot if started from runlevel 3.
- Boot log shows 34 lines such as "*BAD*gran_size: 64K chunk_size:
8M num_reg: 10 lose cover RAM: -2M" (benign??)
System details:
- Asus P8H67-V/R3 (latest Bios 0712, default settings except AHCI and
VT-enabled)
- COREi5/2500K
- 4 x 4GB Corsair CMX8GX3M2A1333C9
- On-board video and ethernet (eth1, at11c driver)
- One additional RTL8139 or Broadcom BCM5702X ethernet for eth0 (fails
identically with either)
- FC14 with 2.6.39.2 custom kernel, updates to 30/6/11
I've tried the following kernel options:
- pci=noacpi
- acpi=noirq
- irqpoll
None have any effect on the IRQ problem.
I've tried moving the ethernet board to another slot. Apart from
changing the IRQ from 16 to 19, no effect.
For the video problem, I've tried i915.semaphores = 0 and 1, but no
difference.

Is the paravirt_read_tsc in the trace ok?? It is just a kernel that
includes the paravirtualised drivers running on bare metal...
Apart from these problems it's great. Power management is really good.
Graphics I can live without for now (it's primarily a server). But the
lack of second ethernet is a killer.
Any ideas gratefully accepted. Happy to try things.
Please CC me directly on any replies.
Many thanks
Chris
