This is _probably_ caused by an IRQ storm, as the IDE code (which is
used for your Compact Flash) raises an IRQ in it's probe routine
but hasn't installed a handler.
The proper patch for this is ignored by Linus and Marcelo since August 2000.
Though Andre has acknowledged the bug and my patch is included in
his latest ide patches.
