Bug#390409: rosegarden: "System timer resolution is too low"
Package: rosegarden
Version: 1:1.4.0-1
Severity: normal
I'm running JACK 0.2.20 on a PII-255 with 256 MiB RAM and a kernel
rebuilt with Realtime-LSM, pre-emption and PII optimisations. The kernel
is left with 250Hz resolution.
On startup, I get the message:
System timer resolution is too low
Rosegarden was unable to find a high-resolution timing source for MIDI
performance.
This may mean you are using a Linux system with the kernel timer
resolution set too low. Please contact your Linux distributor for more
information.

I get the same error if I rebuild the kernel with 1000 Hz ticks.
On boot-up I get the message:
Oct 1 04:04:48 localhost kernel: PCI: Probing PCI hardware
Oct 1 04:04:48 localhost kernel: PCI: Probing PCI hardware (bus 00)
Oct 1 04:04:48 localhost kernel: * Found PM-Timer Bug on the chipset.
Due to workarounds for a bug,
Oct 1 04:04:48 localhost kernel: * this clock source is slow. Consider
trying other clock sources
Do you have any advice about this error?
Regards...
