Firt of all Hi everyone cause this is my first message to this list, ok i
can go on now...

I got a new fresh IBM Netfinity x220 series machine which has a AIC-7892
SCSI controller integrated onboard, that my problems begin.

I got this message and mysqld ending with signal 11 when i stress the
machine:

I've downgraded the SCSI Sync Negotiation (from the SCSI BIOS) to 80MB/s and
the messages disappears but mysqld continue to end with signal 11 under
stress test.
