SCSI Errors and Resetting
Hi,
First off: _very_ cool list! Lurking here has been exceedingly helpful.
We're running Debian 1.3.1 (bo, kernel 2.0.30) on an Intel "Premier
PCI II" motherboard, with a 90MHz Penti, 32MB, BusLogic BT-948, and
Quantum Fireball Drive. Several times a day we get messages on the
console describing a SCSI error, the system is momentarily frozen,
and then everything is fine . . .
On bootup it looks like this:

Sorry about the length of this post, it wasn't meant to be textual
harassment.
TIA,
