Looks like there's been a request to flush the entire Translation Lookaside Buffer, but upon flushing the cache, we bugchecked with a machien check exception. Something has gone wrong in the cache, most likely, and the registers haven't been affected, which is probably why we got a 0x9C and not a 0x124.

The flushing cause is unknown, but ti can be as simple as a context switch, which invalidates a lot of page table entries, thus requiring to flush the TLB.
This looks almost certainly like a CPU failure. As do most 0x9Cs.
Is your CPU still under warranty? If so, I recommend you RMA it.
