OK, now I was able to trigger the bug during a running KDE session. So I withdraw my statement that the problem isn't reproducible once the boot process is finished. I also suspect this bug being the reason that entering Suspend to RAM fails with a flashing Caps Lock LED since 2.6.39-rc5. Suspend to RAM worked flawlessly with .38. Does 2.6.39-rc6 fix it? (In reply to comment #4) > Does 2.6.39-rc6 fix it? Apparently, yes. I can't reproduce the panic with 2.6.39-rc6, and suspend works again. Thank you! Thanks for the update. |
Created attachment 56292 [details] lsusb -v I've configured acpid to issue the above given command when I press Fn+F6 to disable the BT module built into my laptop. Running 2.6.39-rc5, the kernel panics when I press Fn+F6 during startup, preferably when X/gdm is starting. I wasn't able to reproduce the problem once the system was "settled". I never faced this problem in 2.6.38 or any prior version. Attached you find a photo (sorry for the bad quality, but it should be readable) of the messages and the lsusb output. Steps to reproduce: - Turn on the laptop. The bluetooth module is activated by default. - Press Fn+F6 after acpid is started, i.e. while gdm is starting - watch the kernel panic Hardware: - Thinkpad Z60m Software: - Gentoo Linux - if you need version numbers of some particular userspace programs, let me know
