Nick, we need a lot more information than that to even start diagnosing. 
To begin with, compile a kernel with DDB, then try to ctrl-alt-esc into 
the debugger and run a trace to see what the system is doing.

I Was Having The Same Problem After Upgrading From 4.3-STABLE To 4.5-STABLE.
When The Uptime Would Near 24 Hours I Would Get A Kernel Panic And A Reboot.
It Seems To Be inet6 Related. When I Compile The Kernel Without "options
inet6" Everthing
Returns To Normal.
I Have 2 3Com 3c905B-TX Nics Installed.
Here's What I Got From The Dump.
If You Need More Info Let Me Know.

Nick,
Does this problem still trouble you
with 4.6-RELEASE or 4.6.2-RELEASE?

- Giorgos

Haven't attempted 4.6 yet, the bug is on a production machine that I don't
currently have a replacement for.

Why is the author of osdep.c trying to cram two strings into a one-dimensional array?

Asked Originator whether problems persists.

Nick,

do you still experience the problem described in your problem report 
with 4.9 or 5.2?

Thanks

No response from Originator.  According to the backtrace the 
problem happend in IPv6.  There have been many changes to it 
since 4.5.  Judging from the lack of other problem reports 
and discussion this has been fixed.
