Hi,
I think I've found a stability problem in the SCSI subsystem of actual
kernel 2.4.2.
The setup:
Dual-Pentium2 512MB RAM
onboard Adaptec Controller AIC7895 (Dual Channel)
3 internal disk IBM DDRS-39130D
1 external disk easyRAID II with 360GB net capacity
The easyRAID II is a RAID system that works with IDE-Disk and has an
SCSI interface to the outside world. This RAIDs SCSI interface is a
Symbios 53C895.
Moreover the system contains 2 network cards and a graphics card.
I use SCSI low-level driver for AIC-7xxx built into kernel.
I have updated all the necessary tools as described in the
Documentation/Changes file.
gcc-2.91.66
binutils-2.10.1
util-linux-2.10s
e2fsprogs-1.19
The problem occurs when I try to create a file system (or copying lots
of files to the existing filesystem) on the internal disk or the
external RAID after a while there a lot of read error on the disks
reported, and the system becomes unusable, and mostly the external RAID
crashes.
After a reboot of the machine and resetting the RAID box, everything
seems to be fine, and also there are no disk error. I can run three or
more badblocks scans in parallel and all sectors are OK, but when I now
try to create a file system (ext2 or reiserfs) the same stuff as
described above happens.
Then I test another setup with
Dual-Pentium3 with 1GB RAM and Adaptec 29160 SCSI-controller and the
same disks and the RAID box connected, but the same errors came up, when
I try to write large amounts of data, disk reads causes no problems.
Little writes to the disk, i.e. editing a file and saving it, also
causes no errors (in both described setups).
The problem is definitly away when going back to 2.2.18.
Perhaps it is a similar problem like with kernel 2.2.13 that doesn't
recognize IBM DDYS-T18350 disk, but 2.2.18 do.
Thanks for advertence.
With best regards
