We have run into different problem (for our different from S28*arch)
for the box which had had badpmd issues with v2.6.11 (see:
    http://seclists.org/lists/linux-kernel/2005/May/6369.html)

with 2.6.12-rc5 we are always getting dozens of user-space segfaults:

during the build of mysql.

There also was an oops with v2.6.12-rc3 for the same box:
http://seclists.org/lists/linux-kernel/2005/May/6369.html

Box passed two iterations of memtest86 (unfortunately this
is a production box, so we can't wait for days).
