It's mounting all of the partitions fine. I've tried the AIC7xxx modules
both as modules (using initrd) and compiled directly into the kernel.
At first, I thought it was a problem with klogd since I was seeing the
hang just after it told me that the kernel logger was started sucessfully.
This turned out to be wrong since I once started both syslogd and klogd
manually without any imediate problems. The system did eventually hang. I
rebooted the machine after that and left syslogd and klogd off and the
system still went into a hang.
The boot process will sometimes complete normally and I can log into the
box. But it doesn't last. The system eventually hangs without any warning
or messages being displayed.
One other thing I've noticed is that if I go through the interacive bootup
the system will boot to a login prompt every time. It hangs eventually.
I will try to get a dmesg off of the box but I am currently having an
unrelated issue with the network card that I won't be able to clear up
until Monday.
I know I've miscompiled the kernel I'm just not sure where. I did run
across an article in the SMP-HOWTO that says that odd hangs can occur with
some protocol issues. I have compiled SMP support into the kernel but I am
not using multiple processors at the moment. Could that be the problem? If
not, could it be the preemptable patch? Or both?
