[Prism54-devel] kernel oops with linux 2.6.8-rc2

[Henrik Persson]

Been running different -bk-snapshots for some time and I never had this
behaviour with 2.6.7-vanilla.

And then the keyboard(!) goes dead and the only thing I can move is the
pointer. Then it's just powerbutton (acpi-button) for shutdown.. Has
happend a few times over the last week or so.

Saw that this was discussed on the linux-kernel mailing list. Any
thoughts/solutions?
