Recheck and replace if necessary. SCSI cables are fickle to say the least. Upgrades with changes to the adaptec drivers tend to improve the timings and peformance at the expense of breaking marginal setups. Justin Gibbs would have to analyze the dump to confirm my analysis, but this type of problem is pretty common. Its a remote possibility that an updated driver also tickles a bug in your drive's firmware -- I've seen this with an AIT-2 drive. You might check with the drive manufacturer if there is an update. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
