kernel panic  with  kernel version  2.6.9-78.ELsmp.  The kernel panic is very

Actual results:

Could you please try 78.1 or 78.2 from

http://people.redhat.com/vgoyal/rhel4/RPMS.kernel/

and report back with results.

The sys_times patches were reverted in 78.1.

Thanks,

P.

Hi P.

These are production systems, there is already a great deal of unease with the
kernel panics already from the last kernel release -20. It will be difficult at
the moment to test a unreleased kernel with no assurance of reliability. Please
clarify this statement "sys_times patches are reverted" do you mean the sys_time
patches are removed in 78.1 ? 

thanks

Jimmy
