Folks, Several people responded to my previous note with good suggestions for providing more complete information on my problem. Here's a recap of my situation, with what I hope will be more helpful info from dmesg and /var/log/messages.
I've installed Potato on a Mac 7500, a two-scsi-bus, OldWorld machine. When I'm doing a large file copy from one Mac to the Debian box via SAMBA (and FTP too!) the collision lights on my hubs go nuts and the Debian machine's monitor fills up with line after line of SCSI I/O error messages. The errors don't seem to be completely recorded in /var/log/messages, but here are the details from that file: -------------------------- Jun 16 15:29:13 lumper kernel: SCSI disk error : host 0 channel 0 id 1 lun 0 return code = 8000000 Jun 16 15:29:13 lumper kernel: [valid=0] Info fld=0x0, Current sd08:08: sense key Illegal Request Jun 16 15:29:13 lumper kernel: Additional sense indicates Invalid field in cdb Jun 16 15:29:13 lumper kernel: scsidisk I/O error: dev 08:08, sector 2910008 Jun 16 15:29:21 lumper kernel: SCSI disk error : host 0 channel 0 id 1 lun 0 return code = 8000000 Jun 16 15:29:21 lumper kernel: [valid=0] Info fld=0x0, Current sd08:08: sense key Illegal Request Jun 16 15:29:21 lumper kernel: Additional sense indicates Invalid field in cdb Jun 16 15:29:21 lumper kernel: scsidisk I/O error: dev 08:08, sector 2920472 Jun 16 15:29:26 lumper kernel: SCSI disk error : host 0 channel 0 id 1 lun 0 return code = 8000000 Jun 16 15:29:26 lumper kernel: [valid=0] Info fld=0x0, Current sd08:08: sense key Illegal Request Jun 16 15:29:26 lumper kernel: Additional sense indicates Invalid field in cdb Jun 16 15:29:26 lumper kernel: scsidisk I/O error: dev 08:08, sector 2928744 Jun 16 15:29:48 lumper kernel: SCSI disk error : host 0 channel 0 id 1 lun 0 return code = 8000000 Jun 16 15:29:48 lumper kernel: [valid=0] Info fld=0x0, Current sd08:08: sense key Illegal Request Jun 16 15:29:48 lumper kernel: Additional sense indicates Invalid field in cdb Jun 16 15:29:48 lumper kernel: scsidisk I/O error: dev 08:08, sector 2958584 Jun 16 15:51:11 lumper syslogd 1.3-3#33.1: restart. -------------------------- Here are the details from dmesg: device tree used 31448 bytes Total memory = 32MB; using 128kB for hash table (at c02a0000) Linux version 2.2.19 ([EMAIL PROTECTED]) (gcc version 2.95.2 20000220 (Debian GNU/Linux)) #1 Sat Apr 14 23:20:24 CDT 2001 PCI bus 0 controlled by bandit at f2000000 Cache coherency enabled for bandit/PSX at f2000000 PCI bus 1 controlled by chaos at f0000000 pmac nvram is core99: 0 System has 32 possible interrupts GMT Delta read from XPRAM: -300 minutes, DST: on via_calibrate_decr: decrementer_count = 125005 (750033 ticks) Console: colour dummy device 80x25 Calibrating delay loop... 399.76 BogoMIPS Memory: 29624k available (1664k kernel code, 1312k data, 168k init) [c0000000,c2000000] Dentry hash table entries: 4096 (order 3, 32k) Buffer cache hash table entries: 32768 (order 5, 128k) Page cache hash table entries: 8192 (order 3, 32k) POSIX conformance testing by UNIFIX PCI: Probing PCI hardware adb devices: [2]: 2 1 [3]: 3 1 Linux NET4.0 for Linux 2.2 Based upon Swansea University Computer Society NET3.039 NET4: Unix domain sockets 1.0 for Linux NET4.0.
