I'm running 3.0 current. I use an Adaptec 1505. To the scsi card I've attached an Iomega Jazz drive and a HP 6100cse scanner. The Jazz drive works great! However any attempt whatsoever to access the scanner causes an immediate, complete **lock-up** of my system. No warnings of any kind; it just freezes over. (I have tried sane, xvscan and hpscan). My kernel contains: controller scbus0 at aic0 # Single bus device device sd0 device pt0 at scbus? My /dev/directory contains: crw------- 1 root wheel 61, 0 Apr 1 19:07 pt0 crw------- 1 root wheel 61, 0x20000000 Apr 1 19:07 pt0.ctl and lrwxrwxrwx 1 root wheel 8 Apr 1 13:34 scanjet@ -> /dev/pt0 lrwxrwxrwx 1 root wheel 8 Apr 1 18:51 scanner@ -> /dev/pt0 During boot-up, I get the following: Apr 1 19:06:20 lsmarso /kernel: aic0 at 0x140-0x15f irq 9 on isa Apr 1 19:06:20 lsmarso /kernel: aic0: waiting for scsi devices to settle Apr 1 19:06:20 lsmarso /kernel: scbus0 at aic0 bus 0 Apr 1 19:06:20 lsmarso /kernel: sd0 at scbus0 target 4 lun 0 Apr 1 19:06:20 lsmarso /kernel: sd0: <iomega jaz 1GB H.72> type 0 removable SCSI 2 Apr 1 19:06:21 lsmarso /kernel: sd0: Direct-Access Apr 1 19:06:21 lsmarso /kernel: sd0: ILLEGAL REQUEST asc:24,0 Invalid field in CDB Apr 1 19:06:21 lsmarso /kernel: sd0 could not mode sense (4).

It looks OK to me... Any suggestions, as to what next steps I should take to diagnose and solve the problem? (If the next step is, "buy an Adaptec 2940", I guess I can live with that ... if someone can vouch that this is probably the issue). Best regards -- Larry S.
