Description Graham Leggett 2008-03-04 00:45:49 UTC

Install an RHEL5 system on an Intel board with onboard LSI SAS controller. Use
Intel provided driver disk to provide the required SAS driver module.

Use yum to update the kernel, reboot the system.

The system panics, as it cannot find the SAS drives to boot from.

Off to the rescue disk, recreate the initrd with mkinitrd, and the system boots.

Looks like the kernel upgrade mkinitrd procedure is toasted.

Graham -- is it possible that you modified /etc/modules.conf ?  Also what
versions of RHEL5 did you upgrade to and from?

Thanks,

P.

As I recall it was an installation of RHEL5.1 from the installation ISOs. No
changes were made to /etc/modules.conf.

The kernel update was done to bring the system up to date with most recent
updates as per RHN.

Not been touched since 2008 so I think we can assume problem has gone away
with later releases. If not, please open a new BZ.
