Has anybody else been experiencing problems with F10 hanging?

[Kevin Martin]

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.

Thanks.
