dmesg from v3.4 with CONFIG_PCI_DEBUG

This dmesg is the result of following Clemens's advice: boot with firewire_ohci blacklisted, increase the log level and then manually load it.

I was unable to boot with 'debug', because each time I did so, I got a backtrace (*).

Please let me know if there's anything else I can provide to help.

(*) When booting with 'debug', I experienced repeatable crashes: 1 oops and several bugs at kernel/timer.c:1085. Crashes also occurred without 'debug', but not 100% of the time. The stack trace varied, so I'm suspicious (I intend to check the machine's memory). I also reproduced the crash on a stock Ubuntu 3.4 kernel, but failed to do so on a stock Ubuntu 3.2.16 kernel.

Assuming this isn't my machine being unreliable, what's my next step for this issue?

Thanks,
Rob
