Really want to know which bit causes the problem. > Good question. And I think you will find my new finding even more confusing: With your two patches from this e-mail, I could suspend+resume 3? with no problems.. With just your two debugging patches applied. Lovely heisenbug here. I'll add that for every test so far I've removed the kernel source tree, re-untarred it and applied the patches from your e-mails on that, so the tests should be consistent. As is the bug normally, before we started testing patches the crashes were already always *very* reliably happening exactly after the third resume. Just to be sure this morning was not a fluke, I've retested your patch from this morning, and still a crash on the second resume. > Please check debug patch...that will print out pci conf space before > ...and after... > http://gaast.net/~wilmer/.lkml/good3.17-patched-megadebug.txt Wilmer v/d Gaast. -- +-------- .''`. - -- ---+ + - -- --- ---- ----- ------+ | wilmer : :' : gaast.net | | OSS Programmer www.bitlbee.org | | lintux `. `~' debian.org | | Full-time geek wilmer.gaast.net | +--- -- - ` ---------------+ +------ ----- ---- --- -- - + -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
