X-Mailer: Mozilla 4.7 [en] (X11; I; FreeBSD 3.4-RC i386) X-Accept-Language: en MIME-Version: 1.0 To: freebsd-scsi@freebsd.org Subject: Unexpected bus free & swap_pager: indefinite wait buffer Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org We're running 3.3-stable from about 10/21/1999 on a machine that we haven't physically touched for about four months. It has a (supposedly good) LVD cable with a terminator at the end of the cable, that came with the Asus motherboard. Last night, the kernel started printing the errors below and the machine became unusable: couldn't login, unresponsive shells, though it did still respond to pings. The blknos reported in the swap_pager message repeated in a cycle (e.g., 8944, 328, 8944, 328...), and every now and then another blkno would be added to the cycle, until at the end (just before we hit the reset button) the cycle was 8944,328,2640,174968,44560,42848,40720,3208,512,3160. Are we losing a disk, or is it some kind of bug, or...? Thanks in advance for any help you can offer. Matt Dec 13 17:35:00 merry /kernel: Unexpected busfree.
