SMP Kernel crash mystery

by antonh last modified 07-Sep-06 11:48 AM

We've been experiencing weekly to fortnightly crashes on our Compaq Proliant ML350 G3. Couldn't for the life of me work out what could be causing them. But I think I've found...

It didn't work

Well, although the symptoms matched, the suggested upgrade to the latest kernel didn't fix the problem. And on further analysis, we don't even have a gigabit ethernet card. So the smp kernel is most likely the problem, but the cause is somewhat different. I'm tempted to just run it in single kernel mode to see if that is the problem.

Why it didn't work

In fact, the new kernel didn't finish installing itself due to a problem running new-kernel-pkg (more specifically mkinitrd). Why?

» No module modprobe found for kernel 2.4.18-27

What the??

Modprobe isn't a module, its a shell script to load a module...

So anyway, it turns out there was a line in /etc/modules.conf that went like this:

  post-install scsi_hostadapter modprobe st

which was supposed to load the tape driver. So I took this line out, ran new-kernel-pkg and it worked. Stay tuned to find out whether this fix will result in massive uptimes :)
