PANIC: vm_page_fault: unhandled page fault in kernel space at 0xdeadbf2b, ip 0x80568f26

[umccullough]

Looks like I got a very similar issue to #2706 (where there is much more info apparently) - it's probably a duplicate but I'm logging separately just in case (feel free to close as such if necessary).

This is using a gcc4-built hrev29087 with an rtl8168 network chip.

Crash apparently occurred unattended after ~24 hours of uptime with Vision running in the background, and dnetc consuming CPU cycles (and probably communicating with the dnetc server for short periods of time every few hours).

Was able to extra info by hooking up the serial cable:

Machine is still running and sitting in KDL. If there is any further useful info that can be obtained - let me know.

Another crash on gcc2 Haiku hrev29228 - with a nicer looking stack trace - crash initiated from Vision.
