Hi,
Hardware - Iwill's P55TU moderboard ( Intel 430HX chipset ) with onboard
adaptec 7880. Chip labeled as AIC-7880P. I haven't apparent problem, if
try to run fast-narrow devices, but can't set setup to ultra mode.
In this case server run some time ( from 5-10 min to 1 day ) and hangs.
Tested two motherboard, first 2.0 hardware release, second - 2.1.
After test i try to upgrade both moderboard's BIOS. Unsuccessful.
Upgrade from 2.1.0 to 2.2.2-RELEASE also unsuccessful.
Native software for dos run fine. Any suggestions ?
Thanks in advance.

This is dmesg output for 2.2.2-RELEASE ( wide mode disabled ):
