i'm using julian's scsi drivers, and have a WangDAT 3200 at SCSI
id 6...

at startup, i see:
ahb0 reading board settings, 
  **ahb0 probing for scsi devices**
  dev0,lu0: type 0:0(direct),fixed 'MICROP  1908-15MZ1077802HZ2P' scsi1
        sd0: 1314MB, cyls 2112, heads 15, secs 85, bytes/sec 512
  dev6,lu0: type 0:1(sequential),removable 'WangDAT Model 3200      01.9' scsi2
        st0: scsi tape drive, 0 blocks of 512 bytes
ahb0 at 0x1000 irq 11 on isa

when i'm dumping large amounts of data to the tape drive, i will eventually
get:
"ahb0:6 device timed out"


any suggestions, comments, ideas?

this is on a 486-50 EISA machine, with *all caches turned off*...
(same thing happens with them on; i checked this first...  8-)



thanks,

chris
