SCSI I/O errors galore, PART II
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:
