Yast found the patch and is applying it now, and I'm waiting for the

months to promulgate patches for windoze!

Please do not toppost. And the first solution to the problem was given
about 5 minutes after it became known. I think Novell was slow. The
problem was known to the public on sunday. The solution should have been
here on mobday already.

It is still strange that a lot of people I know who run Linux are not
aware of it. This is a MAJOR security breach, I would say.

Are you actually having some? Tried badblocks with a non-destructive
write test? What does smart say about the drives condition?

On and ofd, although tests show no problem. This with different mobo's,
different distributions and different drives and this for a couple of
^^^^^^^^^^^^^^^^
years. So my first suspect is always HD.

If it's different drives, unless they are second user drives, I'd have
thought they'd have been quite a way from being the first suspect.

Not necessarily. If it was a module that went missing due to the kernel
upgrade, the second time would refer to the new kernel module.

Uh, why would it be missing with the first reboot and available with the
second reboot?

Because on the first shutdown the module won't be there as the kernel
update will have deleted it. Once the system restarts, the new kernel is
used, along with the new kernel modules.

Well, if you look at it, it is completely different PC's in the end, yet
when looking, it is the drives that give me problems, if anything.

Yes and the sytem hung when it did the restart. So we have:
Running machine : OK
Update of the kernel and such : OK
Reboot shutdown : Ok
Show of the BIOS: Most likely OK, but I was not there. If NOK, no
startup
Reboot startup : Not OK
Hard reboot : OK
Show of the BIOS: OK
Reboot : OK

So there is no 'missing module'. The machine halted during the startup,
not during the shudown.

If so, he can have the power when it is off all the time.

My problems usually start with power supply issues, then thermal issues
with the processors, then drive issues.

Ah. My reading was that it had locked while shutting down to reboot, not
that it had locked after actually restarting.

I read 'terminal' there and though "that is a severe issue, I wonder how
he solved that." ;-)
