My i386 machine is now unstable. After a few minutes of heavy use (lots of disk action) it freezes and can't be coaxed out.
Alt-Fx changes to another tty still work, cntl-t still works.
verbose boot is set, there are repeating messages periodically:
[diagnostic] cache_lock: blocked on 0xde0684a8 80000001 ""

I was able to break into ddb and create a dump with "call dumpsys"
I will upload that in a bit.

This all started after recent kernel/world updates.

After 3 times on the latest kernel, I tried again on the last of Release 3.4 branch.
Same thing.
It's starting to look like a hardware issue. The symptoms are similar to what happened when the Crucial M4 firmware bug was hit.

I uploaded the core.txt here:

Core itself available upon request (71M, I can upload to leaf quickly)
