Public bug reported:
Binary package hint: kernel-image-2.6.15-26-amd64-generic-di
I have an Intel Core 2 Duo 2.4 GHz CPU. When Speedstep is enabled and
the CPU is slowed, the clock runs at 150% the normal speed. The timer
interrupts continue to occur at 250/second as they should, but the clock
runs too fast, leading to various system problems (sound too fast,
lockups, hardware not functioning, etc.). When the CPU is busy (CPU is
at full speed), the clock runs normally. Disabling speedstep fixes the
problem.
Distribution: Kubuntu 6.06 amd64
** Affects: linux-source-2.6.15 (Ubuntu)
Importance: Untriaged
Status: Unconfirmed
