A while back, I had written about repeated kernel warnings of CCB timeouts on one of my machines. The messages are like these, with varying hex values: Sep 30 03:07:18 lorax /kernel: (da0:bt0:0:0:0): CCB 0xc7830040 - timed out Sep 30 03:07:26 lorax /kernel: (da0:bt0:0:0:0): CCB 0xc7830040 - timed out Sep 30 03:07:26 lorax /kernel: bt0: No longer in timeout This card worked flawlessly under BSD/OS, where Buslogic controllers were the preferred devices. The driver under BSD/OS was extremely well done. Simply installing FreeBSD on this box resulted in these errors. The above errors are repored under a recent kernel/world.

My query last December resulted in two replies. One person said running a cron job to sync once per minute cleared his problem with a Mylex 958. Another person said to check cables. I recall someone saying that the drive was going bad, but that was directly to me, not the list. http://www.freebsd.org/cgi/getmsg.cgi?fetch=177791+0+/usr/local/www/db/text/2000/freebsd-stable/20001210.freebsd-stable In the archives, I found a query from July 2000 with similar issues with a Mylex 958. There was one response to it (not linked in the archive) that indicated an older BIOS should be used in the card. I have BIOS 5.05R, which is older than the BIOS in the original query. http://www.freebsd.org/cgi/getmsg.cgi?fetch=907153+909002+/usr/local/www/db/text/2000/freebsd-stable/20000709.freebsd-stable http://www.freebsd.org/cgi/getmsg.cgi?fetch=1089306+1092247+/usr/local/www/db/text/2000/freebsd-stable/20000709.freebsd-stable Also, from December 1997, I found a message regarding older Adaptec controllers getting these errors under load. This person said as far as he can tell it is a driver issue, since the cards work fine with other operating systems, similar to my experience. http://www.freebsd.org/cgi/getmsg.cgi?fetch=0+2928+/usr/local/www/db/text/2000/freebsd-stable/20000618.freebsd-stable Other than these kernel warnings (and the pause caused by these timeouts) the machine runs just fine. It has never crashed either under BSD/OS nor FreeBSD on its own... Does this seem like a driver issue? I kind of feel like it is as it only happens under heavy load. I get the timeouts on the second drive as well when I pound on it. I don't think both drives are going bad simultaneously... Copyright (c) 1992-2001 The FreeBSD Project.
