You were right -- the current problem with 'tip' is separate & different from the
internal modem/SCSI conflict. Let me describe *that* problem: when booting from CD
(or running sysinstall from shell), sysinstall locks the machine with the open for the internal sio.
I know this from running sysinstall under gdb and finding the system call which locks the machine
(an open).

So I took your advise, removed the SCSI controller, disabled the printer & ttyb (?). Still locks
when I access the internal modem via tip. I have attached the new dmesg.log. (And I would be
interested in knowing how one controls interrupts, etc, assigned to these "PnP" cards)

Sorry I seem so clueless on interrupts/memory/etc. I come from 15 years of Sun admin &
might have to run down panics, but never "lockups". Panics are so much easier as the disks get
synched which means that any kernal traces you had running are written out so finding out what
syscall caused the panic (or even breaking into kdb) is a snap.

Thanks for the help.

Hi,

My machine locks up tight whenever I access my internal modem. The modem
is a standard modem (which works when the scsi controller is removed) and
the scsi controller is an Adaptec 29160 with a DAT drive attached.

Whenever I type "tip dial" (from /etc/remote:
dial:dv=/dev/cuaa4:br#38400:pa=none:) the box immed locks. Mouse doesn't
work. Alt-ctrl-del doesn't work.

However, tape drive works fine.

Any thoughts? dmesg attached.
How is this related to your SCSI controller?  It is not sharing an
interrupt or any other resources with your internal modem.


No, but the modem is sharing an irq with atapci1, which
has the boot drive hanging off it.

Questions.

What does the dmesg look like without the SCSI card?
How is it different?

You appear to have a PS/2 mouse.
Why are both COM ports enabled?

If you don't have a printer, turn that port off too.

You have way too much stuff in this box <bg>
