Bjoern,
We're seeing something very similar to the following with pf and IPv6:
similar to what?
We're seeing the "must be migratable" part of the panic, but nothing else.
It would be helpful to include more data in your problem reports.
What freebsd release?
Yeah, sorry, not my best effort, but we were in the middle of a crisis.
:) This is 8-stable (post 8.2-RELEASE) i386.
Can you reproduce it? If so, how?
Not at will, but it's happened twice now.
panic: 0xc63dd000 must be migratable
cpuid = 1
panic: 0xc63dd000 must be migratable
cpuid = 1
panic: 0xc63dd000 must be migratable
cpuid = 1
panic: 0xc63dd000 must be migratable
cpuid = 1
panic: 0xc63dd000 must be migratable
cpuid = 1
panic: 0xc63dd000 must be migratable
cpuid = 1
panic: 0xc63dd000 must be migratable
cpuid = 1
This is the bit we see. Breaking to the debugger hasn't worked, and
dumping is not an option (I inherited this system, trying to get it
tuned up now).
Depsite being in the subject that's just follow-up problems, though
thinking about it (very wild guess) -- how many cores do you have and are you
running with flowtable enabled?
It's an SMP system, and yes, FLOWTABLE was in the kernel config. I took
that out, and got the KDB options sorted out so that if it happens again
hopefully I can get a stack trace. Thanks for the FLOWTABLE suggestion,
wish I'd remembered that one myself. :)
