Hi all, I wanted to check the level of interest regarding FreeBSD PR kern/6102... I wasn't actually aware that this could be the problem I was experiencing until early this morning. First off, for reference: (a full dmesg and kernel config are at the end) nemesis(walter) 2% uname -a FreeBSD nemesis.fortean.com 2.2.6-RELEASE FreeBSD 2.2.6-RELEASE #0: Thu Jun 4 18:04:02 EDT 1998 root@nemesis.fortean.com:/usr/src/sys/compile/NEMESIS i386 This machine is a PPro-200 with a DPT 3334-UW SmartRaid Controller. After I added a Sony DDS2 DAT backup which runs a dump every night at 4am I started experiencing random reboots about every other week or so. These resets always occurred during the heavy SCSI IO related to the backup. Since the system would just reset, I had nothing to go on until this morning when the system failed to sync the disks and the dreaded: panic: biodone: buffer not busy messages was on the console. After scanning through the mailing lists and GNATS db, I found PR#6102 regarding this (and PR#5117 which is apparently the same prob for 2.2.5) I noticed the problem is not assigned (not surprising, people are busy) but wanted to find out if anyone is working on it and provide them with my datapoints. I did notice the problem seems to not be directly related to the DPT insomuch as it has popped up on other SCSI controllers as well. PR#7424 may also be related, although it seems to deal specifically with the adaptec controller. There have also been reports that switching to CAM fixes the problem (which is not an option for me until 3.0 becomes 'stable' :) This is a fairly serious problem for me, so if there is anything I can do to speed it's resolution, please let me know. - Bruce ======================================================================== || Bruce M.
