Panic on Dockstar (sheevaplug) with netbsd-7

Hello all,

I just had a panic on my Dockstar. I compiled the kernel from netbsd-7 source synched about a few hours ago, and it has a userland from earlier today. I added the athn driver because that's the USB wifi device I want to use. The kernel was cross compiled on an i386 machine using the -m evbarm flag (is this right?).

Here's what it looks like:

uvm_fault(0xc058a150, 0, 1) -> e
Fatal kernel mode data abort: 'Translation Fault (P)'
trapframe: 0xc7e71e38

I was using hostapd in the foreground to try to troubleshoot a problem and when I tried to do a regular kill (kill <pid>), the panic happened.

Unfortunately I don't have the skill to find the problem and fix it.

I'm rebooting it now so I can try to continue to use it.

As an aside: I said in an earlier post that userland programs were crashing when I was using the evbarm-arm userland. This evbarm-earm userland didn't seem to have the same issues such as dhclient and nslookup crashing.
