[Gnoppix-user] scsi boot hangs

[Ingo Schnieders]

Hi,

I tried to boot from gnoppix_0.6.0_beta3 DE intl

During boot process the system hangs. It seems
that the module "aic7xxx_old.o" tries to reset the
SCSI bus several times but nothing happens.

To boot KNOPPIX 3.3 is no problem.

Any idea to solve this problem ?
