Hi Christopher, thanks for your reply!
May I ask whether the nature of your crashes involve network code?
No, it's likely more a filesystem issue. I posted earlier on the tenth in
the message "unstable kernel after update to CentOS 4.5" about it.
From 6 kernel dumps 5 were with process dovecot-auth, one with "mv". As
dovecot-auth accesses user's home directories I assume it could be related
to the corruption problem (which seems to be fixed, though, after I did a
repair of that partition, it seems the earlier boots reflagged the
filesystem as clean, but didn't repair it) I describe in that message.
If I go back to the old kernel and the problem persists it's not related to
the new kernel but probably indeed a hardware problem.
That would be it won't it?
The only packages that may possibly not work with older kernels are
packages related to the kernel like iptables or kernel modules. You
should not have to worry about iptables as it has not been updated since
release. I cannot say much else than that since I do not know what is on
your box.
Hm, kernel modules are coming with the kernel package as well, arent't
they? And they are still around (in /lib/modules) unless I uninstall them,
right? I didn't install or compile any extra modules. Are there other
packages beyond iptables that hold modules? This is a non-X webserver-type
machine, not clustered, simple IDE. So, should likely be fine to revert?
I take it then that you do not have any third party modules then. In
which case, it will be just fine to reboot with an older kernel. Just
change the default entry set in grub.conf.
