re: poweredge 2400 smp kernel process hangs

[Anne & Lynn Wheeler <lynn garlic com>]

I guess i spoke too soon; kernel-smp-2.6.12-1.1435_FC5
finally had a hang after 24hrs ... and finally had to reboot to the 
non-smp kernel. it feels like it is network related ... but it might be 
scsi ... it is usually firefox, mozilla, or thunderbird that starts of 
hanging ... and finally have to reboot to clear (I suppose the 
application could be hanging on some log to scsi drive ... but it feels 
like network related).

poweredge 2400, dual 1ghz processor, 1gbyte memory, six scsi drives, 
raid controller.

problem appeared with all 13xx smp kernels ... i could reboot back to 
1276 smp kernel with no problems or to any non-smp kernel with no 
problems. 13xx smp kernels would frequently hang before getting thru 
login initialization (I upgraded to FC4 final and the accumulated 
changes no longer allowed 1276 smp kernel to boot).

14xx smp kernels now tend to run for some time before a process hang occurs.
