Description of problem:
Using kernel-2.4.9-7 (the first update on 7.2).
I have 2 scsi cards in a Dell PowerEdge 2300 an AIC 7890 (scsi0), which
runs 3 hard disks (no problems so far) and an AIC 7860 (scsi1) which runs a
CD ROM (id5) and a DAT tape drive (id6). During the writting of a backup
tape yesterday the following error occured:
(scsi1:0:5:-1) Unexpected busfree, LASTPHASE = 0xe0, SEQADDR 0x48
This actually seems to come from the CD drive
After that my /var/log/messages was filled with:
(scsi1:-1:-1:-1) Referenced SCB 255 not valid during SELTO.
SCSISEQ = 0x5a SEQADDR = 0x9 SSTAT0 = 0x10 SSTAT1 = 0x8a
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Sorry, didn't try - I am a bit afraid this might not try to do something
also to my hard disks.
The system still worked fine after this problem - I could read tapes, ...
just that the /var/log/messages was growing at an unbeliveable rate - due
to all those messages.
We fixed a scsi tape bug in the 2.4.9-13 errata kernel...
This has not happened again since the upgrade to 2.4.9-13
