SubjectRe: Machine crashes right *after* ~successful resume
Hello Yinghai,

Thanks again for your time!

I've applied your two patches, and as a wild guess also added pci=dump
to my kernel cmdline though I guess that just gave me a boot-time dump -
which mostly didn't make it into my dmesg.

I accidentally booted with no_console_suspend on the first run, which
still caused no output at all on the failed resume. I'm including the
output of that anyway, but also I have a run with that flag removed, and
annoyingly the crash appears to happen before the dump during the crash
finishes - while dumping info for this device, it seems:

04:00.0 PCI bridge: Integrated Technology Express, Inc. Device 8892 (rev
10) (prog-if 01 [Subtractive decode])

(More info in my lspci.txt)

Wondering what device that is exactly, I stumbled upon
http://sourceforge.net/p/linux1394/mailman/message/29755048/ where
someone describes it as a "cheap and crappy PCI bridge". More and more I
wonder if I should just buy a new motherboard - sadly this one wasn't
even that cheap. :-( Though I don't know if the output stopping while
dumping output for this device means that it is the culprit, is printk()
to the serial console in any way blocking/buffered?

Anyway, dumps are in:

Cheers,
