Made a brand new kernel using the same kernel konfig file, because Justin suggested so ... to make sure, that his last changes are in. I made a backup of /bin using tar. No problem. I tried to make a backup of / and /var usging dump... The first time I tried that caused only the messages, that I already wrote in my initial bug report. Then I dumped a minute after that agin / and /var. There were many many messages, that flushed over the screen, so I was only able to write down some, when the flushing finished... Bad news, with the default syslog.conf settings (I made sure to use the newest -current version), completely nothing was logged in the /var/log/messages file. Could someone please tell me better settings, so that I can send you a more complete list of what is going on ... Or do you think, that perhaps syslogd was unable to write to the disk, what could also be possible ... Before that messages below, there were additionally some messages indicating, that the scsi bus was reconfigured to use asynchronous data transmission. sd0(ahc0:0:0) timed out in message in phase SCSISIGI == 0x86 kernel: Ordered Tag queued sd0(ahc0:0:0) timed out in message in phase SCSISIGI == 0x86 st0(ahc0:4:0) abort message in message buffer st0(ahc0:4:0) timed out in message in phase SCSISIGI == 0x96 Ordered Tag sent ahc0: Issued Channel A Bus Reset, 3SCB's aborted. ... ----- Ordered Tag set panic: ahc0: Timed out command times out again Fatal trap 12: page fault while in kernel mode ... ---- dumping to dev 20409, offset 65536 ahc0: board is not responding cmd fail device bad ---- Then the machine is rebooted. I didn't power down the machine and noticed, that the first disk with SCSI ID 0 wasn't recognized by the 2940 host adapter. Only the other 3 scsi devices (disk 1 on ID1, Tape on ID4 and CD-ROM on ID 6). Please tell me, what I can do additionally, to help you to get the bug fixed.
