I'm seeing this on a T60, where USB devices have been enumerated and Synaptics firmware has been loaded. Kernel is alive but stopped with nothing ready to run (sysrq-t). I really suspect something in the bootup userspace logic, because this happens not just on the fedora kernel, but on other kernels as well (e.g. the RT kernel). I'm trying to figure out who's waiting for an event that either is not going to happen or has already happened and just been missed. Created attachment 333068 [details]
Image of boot hang
I thought this photo might be useful, to add some context to the hang.
Just noting that this continues with kernel-2.6.29-0.148.rc6.fc11.x86_64 The first messages after the hang point, on a successful boot: Console: switching to colour frame buffer device 240x75 [drm] DAC-6: set mode 1920x1200 22 fb0: inteldrmfb frame buffer device registered panic notifier [drm] Initialized i915 1.6.0 20080730 on minor 0 Just noting no change with kernel-2.6.29-0.207.rc7.fc11.x86_64 I suspect this is an issue due to the debug kernels... I'll upload some no-debug kernels, would you please test them? Sure, no problem. I just installed kernel-2.6.29-0.237.rc7.git4.fc11.x86_64.rpm and rebooted successfully four times in a row. For those of you still getting hangs, could you try adding 'plymouth:debug' to the kernel command line and seeing what the output is? I had a machine exhibiting similar symptoms and it wound up being a broken initrd that didn't contain the drivers for the root disks. Just fyi, I got sidetracked by some build failures, but there's a nodebug build in progress here: http://koji.fedoraproject.org/koji/taskinfo?taskID=1238109 I installed kernel-2.6.29-0.244.rc7.git5.nodebug.fc11.x86_64. As with kernel-2.6.29-0.237.rc7.git4.fc11.x86_64.rpm (comment 8), I rebooted several times. Powered off/on/booted. Rebooted a few more times. No problems encountered. I'm closing this issue against rawhide. |
