I just tried 2.2.20pre10. The good news is that it doesn't oops anymore.
The bad news is that Cerberus now reports memory errors. However, the
memory errors don't look like a bad DIMM: I got five reports so far, and
in every case four consecutive bytes of user space memory were
overwritten with what looked like a kernel address:
c0325048, d8e988df, c0325710, dc2abf88 and d8e9df88
According to System.map,
c0324de0 is all_requests
c03269e0 is ro_bits
I attached the full report.
