Comment 3 Dave Jones 2005-11-10 21:56:46 UTC
Mass update to all FC4 bugs:

An update has been released (2.6.14-1.1637_FC4) which rebases to a new upstream
kernel ( As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.

Please retest with this update, and update this bug if necessary.


Comment 4 Øyvind Stegard 2005-11-11 15:18:55 UTC
Sorry, the hardware where this occured is no longer available to me; I've bought
a new laptop. Because of this, I will not be able to test if this bug has been
fixed in recent kernel updates.
