I am still having problems getting a new kernel going with the
latest sup of -current. Here is the guts of my previous message to

I am currently running a July 3rd build of -current, which was about
the time that pppd broke, and so I commented out any ppp support in
the kernel. Now my people are yelling for it, so I need it back. I
also want to get my 'standard' lpt0 (hardware thinks it is at lpt1's
port!) up and running.
The last kernel that I got running was an X insecure kernel
(round the first week of August - just before the scsi quirks code got
added) that I do not want to run now since I configured the X portal

supped the latest sources because I read about some changes in the
ncr and pci code and tried again, this time with in-kernel debugging
turned on. This allowed me to see what was happening before the
The system correctly ID's all devices and gets their sizes and types
including the Quantum HDD. It gets to the line:
biomask 4040 netmask 1800 ttymask 1a
vm_fault(f86f0700,0,1,0) -> 1
kernel: page fault trap, code = 0
Stopped at _nqsrv_getlease+0x148: movl 0(%eax),%ebx
If kernel debugging is turned off I get messages as previously
I am booting a new kernel with a full July 3rd build. Could this
have anything to do with the old/new mount code and a new kernel?
Does anyone have any idea where I should start looking?
I have not done much kernel debugging, so I am at a bit of a loss as
to where to start.
