Hi there. I have been trying to set up a 133-MHz Pentium, dual-Adaptec 2940 
system that I am trying to set up for a news system, which I have configured 
as listed below. A couple of problems have shown up while playing with the 
system:

1) The Adaptec cards are probed one way by the BIOS, and by NetBSD another. 
The result is that the drive the system would boot from would be on the second 
controller (and thus sd2) when the kernel tried to mount root. This was worked 
around by hard-configuring the drives in the kernel config file, but I'd 
thought I'd mention it as it does seem abnormal.

2) The system tends to crash after it has been up for a while and has recently 
completed a large amount of disk access. For example, it died today shortly 
after 3 concurrent iozones were terminated, after running for close to a day. 
It died yesterday after close to 3 days of running iozone constantly.

The Adaptec driver is the one recently ported from FreeBSD (May 1rst vintage), 
patched against an otherwise vanilla 1.1 tree. The panic which occurs is of 
the form :

_Debugger() +0x4
_panic() +0x3b
_aha_init() +0x130e
_softclock() +0x51
_hardclock() +0x19e
_clockintr() +0xb
_Xintr0() +0x63
--interrupt--
...

I have the arguments to these from the two most recent crashes if that is of 
any use (they are slightly different).

Right now the system is being run with one controller, in the hope(?) of 
reproducing the problem without the possibility of some corruption based on 
the second controller. (The configuration had been working for a couple of 
weeks w/ a single controller in combination w/ a patched -current kernel on a 
1.1 install in a different system (120MHz Pentium)). The thought that it might 
be heat based has come across my mind (the system gets rather hot), but other 
possibilities are being looked into.

Any suggestions on a plan of attack would be appreciated. Thanks.
