I have no idea on what kind of modification openwrt folks do on top of
Linux kernel, but there is a chance the kernel space smaller or change
the way slab/slub/slob allocator works. In essence, the crash might
happen due to memory shortage or something like that.

Can you force a backtrace?

PS: I see no kfree() on the pastebin, is that true?
