Oh noooooo....
2.1.0R is out, so 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 [total of six times]
..
ahc_scsi_cmd0: more than 256 DMA segs
sd0: oops not queued
biodone: buffer already done
/: bad dir ino 2 at offset 0: mangled entry
panic: bad dir
dumping to dev 40, offset 32768
ahc0: not responding
SCSI bus busy light on... system hung.
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!
