Parallels and /dev/rtc error


I get the following error when starting Parallels Workstation 2.2:

Parallels Workstation encountered a problem with the /dev/rtc device. This may be caused by one of the following reasons: (1) you do not have proper system permissions, (2) the device is not found in your host PC, (3) the device is used by another process. The absence of /dev/rtc device may downgrade VM performance and make internal timers slow.

It is running under Mandriva 2007. Everything seems to run fine, even with the error, but I may be taking a performance hit. Permissions for my /dev/rtc are:

-rw-rw-rw- root root

I try to cat /dev/rtc and get:

[falcon56215@localhost ~]$ cat /dev/rtc
cat: /dev/rtc: Device or resource busy

Also:

[root@localhost falcon56215]# hwclock --show

Anyone have any ideas?

i think alsa can/does hold a lock on /dev/rtc
try blackballing snd_rtctimer module and see if it helps
or you might have to recompile kernel without alsa rtc support
