Subject: EIP Errors kernel 2.6.18 .AND hard lockup ... Revisted

Ok, Same stuff, different day. Took the nVidia drivers out.
Ran HOT MEM checks, all passed (elimnating RAM issues).

Same as this time last month.

Got hard lock ups every 2 - 3 days. No syslog / debug ever given -
pdflush ,when top is left running on console - shows 100% CPU usage.

FINALLY got this morning a EIP error :

Problems seemt to have started  when I added at start of summer, a SIL 3112A SATA controller
and a WD 250GB WD2500SD-01K Rev: 08.0 250GB SATA disk.
