It looks OK for a user mapping, assuming you have at least 64MB of SDRAM (the SDRAM starts at 0x10000000) -- all the normal userspace flags are set and all the kernel-only flags are unset. It's marked as executable, so it could be that the segfault was caused by the CPU executing the wrong code.
The virtual address 0x4377f876 is a bit higher than what you normally see on avr32 systems, but there's not necessarily anything wrong with it -- userspace goes up to 0x80000000.
Btw, is preempt enabled when you see this?
