Linville, Larry Finger; +Cc: Herton Ronaldo Krzesinski, linux-wireless Hi, Does either Larry or Herton see the sort of behavior (https://bugzilla.redhat.com/show_bug.cgi?id=891019) on suspend? John, is there anything changed between 3.6.9 and 3.6.11 which would cause this? Other than a genuine kernel regression, it is possible that it might be fedora specific - I just went from F17 to F18. F18 seems to have an systemd integrated udevd which might behaves differently from the older udevd's... or general funniness with F18 (I noticed another bug https://bugzilla.redhat.com/show_bug.cgi?id=891018 but that might be unrelated). Anyway, other than whole sale downgrade I think I can try booting 3.6.9 (which suspended cleanly under F17) and see whether it is a F18-specific problem.

Hin-Tak, My system has never done a suspend/resume with any wireless card, thus I cannot check your result. The test with 3.6.9 is a good idea.

I have since rebooted to 3.6.9-2.fc17.x86_64, 3.6.10-2.fc17.x86_64 as well as 3.6.9-4.fc18.x86_64, 3.6.10-5.fc18.x86_64 and 3.6.11-3.fc18.x86_64; and all have the same problem. 3.6.9-2.fc17.x86_64 was the last kernel which I ran for over two weeks and had suspended a few times according to my /var/log/messages*. So this looks like a fedora-18 specific problems brought on by changes in userland between F17 and F18. (possibly the systemd integrated udevd). I'll add a comment to the bug report and let John reassign as appropriate. Hin-Tak ^ permalink raw reply [flat|nested] 4+ messages in thread
