Hey!
I have encountered tmscsim hangup together with:
Motherboard: ASUS P5A-B Super 7 Motherboard
SCSI Adapter: Dawicontrol DC-2974 PCI (BIOS 3.53)
OS: Linux, kernel 2.2.18pre21, distribution debian 2.2 (potato)
scsi-driver:
tmscsim
Tekram DC390/AM53C974 PCI SCSI Host Adapter,
Driver Version 2.0d 1998/12/25
Because of previous problems the external cache is disabled on the motherboard.
scsi and tmscsim have default settings (see below).
i have two swap partitions, one on each disk (see below).
I don't have further hard disks.
When i induce a memory overflow using
hugs -h128m
(hugs is an haskell interpreter (in debian distribution), and the command tries
to create a heap with 128*8 mb).
from the console, i get the following kernel messages which seem to be ok:
VM: do_try_to_free_pages failed for hugs...
VM: killing process hugs
However, when i start the same command from xterm in a running X environment,
the process is sometimes killed, sometimes not, and i get some scsi driver
message reporting an illegal operation 08d1c410.
The driver than tries to reinitialize several times and eventually stops the
swap device.
(I couldn't fully write down the driver messages because they come too fast.)
Sometimes i've encountered indeterminstic hangups when the swap load is high,
though it doesn't seem to be a real swap space overflow.
I tried to
- slow down the sync speed for the two disks,
- slow down the PCI bus to 25
but that didn't help.
Can i do anything to make my system stable (with DC-2974 or by
buying some other SCSI-adapter?)
Best,
Elke.
