G'day all, Excuse me if this isn't the correct list. I've found various discussions on this topic, including talk of patches and upgrades to bios, etc, but still can't find the definitive answer. I have 2 machines, m1 is my personal workstation, and m2 runs a web server for a customer, and both run 2.2.2-RELEASE. m1 has an AHA-2940U (bios 1.23), 64Mb RAM, 2 * IBM DORS 32160, other bits and pieces, 1 external Jaz. m1 works exceptionally well. m2 has an AHA-2940UW (bios v1.25), 128Mb RAM, 2 * Quantum Fireball ST6.4S (scsi #1 is broken at the moment), 1 internal Jaz. m2 doesn't work at all well. It usually hangs after issuing the messages similar to those below to the console. However on this occassion it was during a boot. It may run for 1 hour, it may run for 1 day, but usually no more. Mind you, m2 was working OK before I put the Jaz drive on. So it could be the termination. Its the last on the chain and I'm using the terminator that Iomega shipped. I can 'soak' the jaz drive by writing/reading large tar files to/from it, and it doesn't break. Walk away and sometime later its frozen. Can someone help me out on this, is it the 2940 bios, the aic7xxx driver, SCSI termination, or something completely different ? I'm quite happy to provide whatever information anyone requires.
