Hello,
Is this crazy|forbidden to do ioremap_wc or
set_memory_(uc|wc) in a device driver suspend
callback ? Right now on AMD Athlon Dual Core
any calls to this functions won't return (when
called from suspend hook).
Cheers,
Jerome Glisse

So it seems it was due to me accessing an unmapped
area (being the console buffer) which triggered the
bug, i was just unable to see message further down.
Sorry for the noise.
