The following reply was made to PR kern/128452; it has been noted by GNATS. From: Kirk Strauser <KIRK@STRAUSER.COM> To: bug-followup@FreeBSD.org, kirk@strauser.com Cc: Subject: Re: kern/128452: [sa] [panic] Accessing SCSI tape drive randomly crashes my amd64 system Date: Sat, 1 Nov 2008 21:16:51 -0500 And other kernel panic dump. Daily crashes while making backups are pretty standard now. This problem started when the machine was an Athlon 1.4GHz. Since then, I have replaced literally every component but the tape drive itself, including an identical model Tekram DC-390F SCSI card (I bought two a while back and swapped cards between servers for testing). Is there any additional information I could provide to help out?
