So looks like a regression. Alas this thing could be hard to debug and
still more data is needed. For the beginning maybe: .config, dmesg,
and a few SysRq logs while this happens e.g. Alt-PrtScr with t, d, w, q
(gzipped or as attachments to a bugzilla report). (If it's not a big
problem trying 2.6.28.9 could be helpful too.)

Thanks,
