I just acquired a Wangtek 5525ES SCSI tape drive. More specifically, it is a: (ahc0:4:0): "WANGTEK 5525ES SCSI REV7 3R1" type 1 removable SCSI 1 st0(ahc0:4:0): Sequential-Access density code 0xc, drive empty (a SCSI-1, QIC-525 tape drive) This is running in a FreeBSD 2.2.2-RELEASE system with an Adaptec AHA-2940AU PCI SCSI controller. Anyway, here's the problem: Sometimes, the tape drive locks up the system. This only happens on commands which actually access the tape drive -- e.g. tar, cpio, etc. Even an "mt retension" will do it, though an "mt status" doesn't (yet...). When this happens, it appears that the tape drive locks up -- the motors don't wind, I can't <ctrl-c> the offending process, etc. BUT the system ISN'T locked -- I can switch over to another VC and login and do stuff. The SCSI bus isn't locked either--I can log in on another VC and access my SCSI CD-ROM, Jaz drive, etc. After a LONG time, the kernel prints error messages similar to the following: Sep 5 15:01:51 DonaldBurr /kernel: st0(ahc0:4:0): NOT READY csi:40,0,0,0 Sep 5 15:04:32 DonaldBurr login: ROOT LOGIN (root) ON ttyv1 Sep 5 15:33:51 DonaldBurr /kernel: st0(ahc0:4:0): SCB 0x2 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 Sep 5 15:33:51 DonaldBurr /kernel: SEQADDR = 0x6 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Sep 5 15:33:51 DonaldBurr /kernel: st0(ahc0:4:0): Queueing an Abort SCB Sep 5 15:33:51 DonaldBurr /kernel: st0(ahc0:4:0): Abort Message Sent Sep 5 15:33:51 DonaldBurr /kernel: st0(ahc0:4:0): SCB 2 - Abort Completed.

Is this a hardware problem, a FreeBSD problem, or an Adaptec problem? I have heard stories of the AHA2940 type cards being unstable -- guess I should have thought twice before buying one. But I really had no choice, as all of my ISA slots were full (otherwise I would've bought a AHA1542, which I'm MUCH more comforatable using). Someone has told me that upgrading the kernel can fix a lot of this (it contains a better aic7xxx driver?). Unfortunately, I'm not sure which version of the kernel to upgrade to, or even how to perform this upgrade (do I need to update the whole FreeBSD system, or can I just download the kernel 'sys' files and rebuild from those?) Please respond by e-mail if possible. Thanks! Donald Burr <dburr@POBoxes.com> - Ask me for my PGP key | PGP: Your WWW HomePage: http://DonaldBurr.base.org/ ICQ #1347455 | right to Address: P.O.
