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:
