Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi - we are having problems with our 2.2.1-RELEASE system freezing regularly, most notably when performing a level 0 dump (but also at other times - perhaps when SCSI traffic is high?). We have 5 slices to back up and somewhere in dumping the third slice (the first big one) it freezes - quite reliably :) Sometimes we have to reboot it (reset switch), sometimes it reboots itself immediately. It has also crashed once on a lot of disk copying, and some other times. System specification: Pentium 120 Triton P5I437P4/FMB chipset Adaptec 2940W SCSI controller SONY SDT-5000 SCSI DAT tape 2* SEAGATE ST15230W SCSI hard disks Cirrus Logic 5430 PCI graphics card . Going to 2.2.1 from GAMMA fixed a SCSI bus resetting -> crash problem which other people have reported, but this freezing thing persists. I have tried GENERIC & custom kernels - both crash similarly. (note: I have been running the system for about 1 1/2 yrs with just a 2.1 system until 2.2-GAMMA. That never crashed. The system only began crashing/freezing after my "upgrade"). The current system was created by running a "make world" on the cvsup'd 2.2.1 source, along with a custom kernel recompilation. I don't have anything to show for it in the logs - (/var/log/messages). Stuff like: /kernel: sd1(ahc0:3:0): timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 no longer occurs since I upgraded to 2.2.1 . I haven't tried kernel debugging or SCSIDEBUG stuff yet partly because I know almost nothing about it, partly because people want this machine up most of the time. I think it's another adaptec 2940 driver problem, and am thinking of trying the newest 2.2-RELENG source, but I don't know whether that's really the problem, or if it is, whether it's recently been fixed. any advice appreciated, thanks, Marcus. -- =-----= Marcus Gallagher->marcusg@elec.uq.edu.au http://www.elec.uq.edu.au/~marcusg/ Electrical & Computer Engineering, University of Queensland Brisbane.
