2.4.1ac3 vs 2.4.1ac8

Basic Machine configuration:

SMP Supermicro board
2 gigabytes of ECC Registered ram
Adaptec AIC-7892
eepro100 onboard nic

The machine has been running as a database server with no MySQL crashes
for several months and has run fine with kernels 2.2.18 and 2.4.1ac3.

We have seen a HUGE improvement in the processing power and file
access from kernel 2.4.1ac3 to 2.4.1ac8, but MySQL crashes every few hours
with the following error on 2.4.1ac8:

mysqld version: 3.23.32

mysqld got signal 11;
The manual section 'Debugging a MySQL server' tells you how to use a
stack trace and/or the core file to produce a readable backtrace that may
help in finding out why mysqld died
Attemping backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong
Bogus stack limit or frame pointer, aborting backtrace

With 2.4.1.ac8 syslog has been spitting out the following errors:

Feb 9 00:15:19 db1 last message repeated 114 times

etc

We would love to stay with kernel 2.4.1ac8 because of the huge speed
increase.
