Subjectkernel 2.4.x bug in adaptec raid modules
Hello,
i use linux slackware 8.1 i386 raise fs and i try some
kernels in my server.
I found problem.
Explain problem:
My raid is Adaptec ATA 2400A IDE. My raid disks is on
UFS file system.
My boot disk (hda1) is on raise fs. I initialize my
raid with:
modprobe dpt_i2o
and i mount them:
mount -t ufs -o ufstype=44bsd /dev/sda5 /mnt/disk
When i copy/move small files (i try with 29 kb file)
from hda1 to sda5
my server is frezzing. Need cold restart. I try with
large files, no problem.

Any body know this problem and have solution for me?
I try latest kernel 2.4.20 but problem exist.

If some fields are empty or look unusual you may have
an old version.
Compare to the current minimal requirements in
