syncing disks ... giving up

From: Frank J. Beckmann <frank(at)>

until a few days ago I used 3.0-current elf with a.out kernel of early
december. Then i updated to a curent current and elf kernel. Since then
my disks can't get synced when I do a shutdown. It says "syncing disks..."
and the number of busy local buffers goes down to 5 or for, but not below
that number. Syncing the disks only succedes in one in about 10 times.

Another problem is related to apm. Halting used to switch my ATX
mainboard of but that doesn't work anymore.

This 2 problems happen with and without SMP enabled.

I have also a SMP problem. I get hundreds of silo overflows under load
with SMP but I don't get that errors without SMP.

Last question is: does rc.shutdown ever get executed?

My hardware is an Intel DK440LX with 2 Pentium II 333.
