My load goes up too but I see a reason:

[jogi@planetzork jogi]$ ps axl | grep -E ' D '
0 500 3179 1 0 0 1728 896 down_failed D ? 0:00 cvs -z9 c
0 500 5724 1 0 0 796 392 down_failed D ? 0:00 du -s . .
0 500 17364 1 0 0 1728 896 down_failed D p0 0:00 cvs -z9 c
0 500 18034 1 0 0 1728 896 down_failed D ? 0:00 cvs -z9 c
0 500 28445 1 0 0 1728 896 down_failed D ? 0:00 cvs -z9 c

My current load is

[jogi@planetzork jogi]$ cat /proc/loadavg
7.00 7.01 6.74 3/92 18550

which is caused by 2 rc5des taking all idle time and those 5 stuck
processes. There were some changes in patch-2.1.130 regarding
down_failed which I don't understand. Maybe this helps tracking down
the problem.

Regards,

Jogi

PS: My system is 2.1.130-SMP with the patch to mm/filemap.c by
Stephen C. Tweedie.

Well, yeah ... I suppose there's no point in getting greedy, is there?
