I'm having tape drive problems...
I'm trying to back-up my 2.0.5R machine to 8mm Exabyte, but every time
I get close to finishing my tar backup, this happens:
ahc0: target 0, lun 0 (sd0) timed out
ahc0: target 0, lun 0 (sd0) timed out
...[repeats]...
SCSI bus hangs, and I'm forced to reboot system...
Rarely, the above messages are followed by:
ahc_scsi_cmd0: more than 256 DMA segs
sd0: oops not queued
biodone: buffer already done
Once, this even happened:
/: bad dir ino 2 at offset 0: mangled entry
panic: bad dir
dumping to dev 40, offset 32768
ahc0: not responding
The machine is a 486DX50 EISA/VESA w/16MB, with an Adaptec 2742AT EISA
SCSI card. Please find dmesg output below... The system kernel is all
generic 2.0.5R EXCEPT it has an updated st.c:
($Id: st.c,v 1.38 1995/07/16 09:13:14 gibbs Exp $).
Anyone see this before... know of a solution?
Any suggestions would be most appreciated... Thanks!
- Mike
