next in thread | raw e-mail | index | archive | help
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
