From: goetzs@uranus.central.de (Goetz Schuchart) Subject: ADAPTEC: SCSI host x timed out - ... HILFE ! Date: Sun, 1 Aug 1993 22:27:58 GMT
I posted this message one week ago - but I did not get
very much help. What I got were many messages from people
who have the same problem:
Many people who use more than one SCSI drive get these
"SCSI host 0 timed out - Aborting command"-errors mostly
caused by heavy disk activity...
I would be pleased if you could forward this message
to the author of the Adaptec drivers for Linux and
for any help I can get with this strange problem (had
crashed my filesystem three times until now... what
meant a lot of work for me...)
--- problem description ---
Configuration:
Hardware:
486DX50-EISA, 8 MB ram, Adaptec 1742 with ST3283N and
ST1096N, AST Fourport, IDE-Controller with Conner and
ST3283A
Software:
Kernel 0.99-pl9
When having really high diskactivity on both scsi-hds
_and_ on one IDE-hd _at the same time_ I get a kernel
panic:
Unable to handle kernel paging request at address c00000cc
Oops: 0000
EIP: 0008:00061P8E
EFLAGS: 00010202
fs: 0017
base: C000000000 Limit: 00200000
Pid 0, process nr: 0
83 bdcc 00 00 00 00 74 14 68
task[0] (swapper) Killed: unable to recover
Kernel panic: Trying to free up swapper memory space
In swapper task - not syncing
SCSI host 0 timed out - aborting command
SCSI host 0 timed out - aborting command
Now I want to give an example when this error
occurs every time:
/ is Conner IDE
/usr/spool is Seagate SCSI (ST3283N)
/mnt2 is Seagate SCSI (ST1096N)
swap is Seagate IDE (ST3283A)
cd /u
find . -xdev | cpio -paduv /mnt2 &
cd /usr/spool
cp Log.o x.x &
cp Log.oo x.y &
sync
All tasks are in background and work at the same time !
Log.o and Log.oo are big files (over 1 MByte)
What I do is backing up the /u tree from IDE-disk to
SCSI-disk and copying two big files on scsi-Disk
all at the same time. This means high disk activity
on three disks.
Every time I do this (as described above) I get this
error...
With kind regards,
Goetz Schuchart
