I'm getting some strange things happening on F10 lately. In a terminal session if I "ps -ef" or "w" or "ls" or anything of that nature the command runs (sometimes) but never returns the prompt. Also, my loadavg seems to go sky high but "top" doesn't necessarily show anything using much CPU (actually, top will often show that my cpu utilization is 90+% idle while my loadavg is upwards of 10). I can usually shutdown my "gui"fied apps (like Thunderbird, Firefox, VirtualBox) but if I try and reboot the reboot hangs while trying to shutdown "automount" and I have to cycle the power on the box. I'm running the latest updates including kernel 2.6.27.15-170.2.24.fc10.i686. Any thoughts or suggestions are appreciated.
Stuff like that usually indicates a kernel bug. Try rolling back to an earlier kernel, and see if it helps.
Perhaps a similar kernel bug that nailed me on one of my x86_64 servers has now migrated to i686 land. On one of my servers, 2.6.27.12 was the first kernel that could actually survive under load. Earlier kernels kept falling apart on me, with processes getting stuck in permanent TASK_UNINTERRUPTIBLE states, which prevented me from updating to F10 from F9. That was barrels of laughs to deal with.
Roll back to an earlier kernel, then just keep trying new kernels as they become released, and cross your fingers.
