Adaptec 2940 and reboot

Applicable to
S.u.S.E. version: all
Kernel version: 2.0.x

Symptom:

The computer runs under Linux, but it cannot be rebooted. The AHA 2940 is not detected or does not find the connected devices either. Only after a physical switch off the hardware is reliably detected again.

Solution:

Try with a kernel parameter, that influences the Linux's reboot behaviour. Possible parameters are:
LILO boot: linux reboot=bios
LILO boot: linux reboot=warm
LILO boot: linux reboot=cold
LILO boot: linux reboot=hard

In some cases (unfortunately not all of them) the parameter reboot=bios helps.

If you are using an AHA 2940 (chipset 7861) activating the Adaptecs's BIOS feature

Plug and Play SCAM support

, which is switched off by default, might help.
