Since my last thread regarding the instantaneous panic

I guess I'm still waiting on the merge to head? ddb is
inaccessible from a usb keyboard so I haven't bothered
consoling to obtain further details assuming your merge
will probably correct the issue.
What is you dom0 ? i386 or amd64 ?
I'm not sure anything in the branch would fix this, but it's worth a try.
Outside of PAE support, do your changes to i386 still occur in head?

What is the panic exactly ?
I don't have any of the details now and not being a dev am not sure what
would be significant from memory ... I do remember seeing uvm fault though.
To get more details from ddb you could build a kernel with
(hopefully it won't exeed 24 lines)
I may have to wait till the weekend to have time to check but that will
definately be a useful option. A laptop with a serial port would be even
better but oh well.
I'm still relatively new to cvs, although I can usually work
out what I need to, what's the cvs incantation for accessing
your xeni386 branch?
cvs -d anoncvs%anoncvs.netbsd.org@localhost:/cvsroot co -r bouyer-xeni386
Thanks for that. I'll stick to head for now though until you say otherwise.
On another note, when I attempted to update userland from 4.99.39, I ran
into libc related problems (libc.so.12 not found) and needed to unpack
sets from an iso (thank you to wheomever decided to include raidframe
support in the install media). Is there a way to avoid these issues? It
has only occurred when updating a dom0 and I have another to update
soon, all my domus updated with no problem. I'm tempted to think I did
Thanks for your help.
