Hi
I need to know which of the AHC_* options are safe in the kernel
config file; I tried one kernel and I got big problems (wrong netstat
output, core dumps and finally a nice cold reboot). I'm not sure that
the system doesn't support AHC options but rather my partitions are
ruined in consistency matter speaking.
I have an Tyan Tomcat III with 2 Pentiums, 64Mb RAM @60ns, AHA2940AU
PCI with an Quantum VP32170. Any hints are appreciated.
The SCSI system looks like this from the view of a normal kernel:

Please not that Steve Passe <smp@csn.net> already assured me that there
should be nothing related to SMP code that might cause problems.
Thanks.
