do you perhaps remember when things started to fail? my guess is that it's probably the per-cpu PGD stuff again that got introduced with UDEREF/amd64 over a year ago (KERNEXEC also enables it, does that affect the results for you?).
If it is of any value I can post my .config file.
yes, that may be useful, especially if i can then reproduce the problem here otherwise i'll need your help to debug it. what's your CPU btw (/proc/cpuinfo)?
