Hi,

The
0x00040004access address almost looks like some pointer-poisoning thing.
It's the result of doing
Quoted 1 line
0: 39 72 04 cmp %esi,0x4(%edx) <=====
when %edx is 0x00040000.
That looks to me like a single bit-flip in memory, and get_hash_table is one of those functions that shows up in traces all the time when you've got bad memory (it's one of the kernel's hottest functions for doing list-walks over dynamically-allocated data structures.)
This footprint would definitely have me reaching for memtest86 as the next step. It certainly has all the hallmarks of a classic bit-flip bad memory trace.
