Hi!
Meanwhile I found out that the problem does not occur when the X86_PM_TIMER option is enabled in the kernel.
Is it OK to enable X86_PM_TIMER? The Xenomai documentation does not explicitly say if this option should be
enabled or disabled, but I've read about some issues on the mailing list where this option caused problems.
Best regards,
Christoph
