Thanks,<br>
<br>
You were right -- the current problem with 'tip' is separate & different
from the <br>
internal modem/SCSI conflict. Let me describe *that* problem: when booting
from CD<br>
(or running sysinstall from shell), sysinstall locks the machine with the
open for the internal sio.<br>
I know this from running sysinstall under gdb and finding the system call
which locks the machine<br>
(an open). <br>
<br>
So I took your advise, removed the SCSI controller, disabled the printer
& ttyb (?). Still locks <br>
when I access the internal modem via tip. I have attached the new dmesg.log.
(And I would be<br>
interested in knowing how one controls interrupts, etc, assigned to these
"PnP" cards)<br>
<br>
Sorry I seem so clueless on interrupts/memory/etc. I come from 15 years of
Sun admin &<br>
might have to run down panics, but never "lockups". Panics are so much easier
as the disks get<br>
synched which means that any kernal traces you had running are written out
so finding out what<br>
syscall caused the panic (or even breaking into kdb) is a snap.<br>
<br>
Thanks for the help.<br>
<br>
