SuSE 8.1 has a known issue with reiserfs that may cause the kernel to
crash and blink the leds. There was an update that solved this. However,
if you can not update, try editing the /etc/fstab file, and on all reiser
partitions add "barrier=none" to the options part; like:

   /dev/hdb6 / reiserfs defaults,barrier=none 1 1

Then, if you update the kernel (YOU) remove that option or they will not
mount. On the other hand, the patched kernel may have problems with nvidia
cards: very very slow 3D - at least that was my case.

This was commented here on the list several times... for example:

Mmm, also have a look at "Support knowledgebase (81_update_kernel) "

If you suspect hard disk problems, and your hard disk supports SMART
(Self-Monitoring, Analysis and Reporting Technology) try:

  smartctl --all /dev/hda |less

(substitute hda as appropriate). On hardisks with smart support this will
show, amongst other things, the logs of the last 5 hard disk failures. If
you want to test your hard disk, do:

  smartctl --test=short /dev/hda

This executes with the HD on line: that is, you work is not interrupted.
It is executed by the hard disk controller, with no OS intervention, and
it takes about one minute. To see the progress and/or results, do:

  smartctl --log=selftest /dev/hda

For the full self test (about one hour), type:

  smartctl --test=long /dev/hda

And to see progress:

   smartctl --log=selftest /dev/hda

For example:

=== START OF READ SMART DATA SECTION ===
SMART Self-test log, version number 1
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Short off-line Completed 00% 4915 -
# 2 Short off-line Completed: read failure 90% 4272 0x0170169c
# 3 Short off-line Completed: read failure 90% 4272 0x0170169c
# 4 Short off-line Completed 00% 1909 -
# 5 Extended off-line Completed: read failure 90% 1902 0x0060da4e
# 6 Short off-line Completed 00% 1902 -
# 7 Short off-line Completed 00% 400 -
#21 Extended off-line Test in progress 90% 4918 -

(test #21 completed correctly, if you are curious)

Of course, this cute program is included on the distro. SuSE 8.2 has it,
and I think 8.1 has it as well. I don't know if the rescue system has it,
though.
