Linux VM completely lost it`s timesource !?

Linux VM completely lost it`s timesource !?

[devzero]

Hi !

I`m running 2.6.24 kernel in a recent version of vmware workstation and i`m unsure if i hit a linux issue or a vmware issue here.

after suspend/resume (hibernate) of my physical system (win xp), the linux guest seems to have lost itŽs timesource.

don`t know much about timers in linux, so let me explain first:

the guest was running when i suspended the xp host.
the xp host is running fine after resume.
the guest has issues.

triggering a console beep inside the linux VM now doesn`t give a short beep but terrorizing me with a never-ending continuous beep.

seems to be a timer issue inside the guest, since tools like top, vmstat, watch etc don`t work anymore.
the system clock gone crazy, too - it`s counting from 22:40:47 to 22:40:51 and then constantly jumps back to 22:40:47

can someone give an advice what to check to make sure that this is NOT a linux issue ?
i will contact vmware then afterwards.

regards
roland

ps:
i did a snapshot of the VM and could preserve the state of the system this way.

Re: Linux VM completely lost it`s timesource !?

[devzero]

cat /sys/devices/system/clocksource/clocksource0/current_clocksource
acpi_pm

cannot switch to any other clocksource, "echo tsc|jiffies|pit >current_clocksource" doesn`t have any effect. 
current_clocksource stays at acpi_pm

maybe somebody has a clue what to check besides this?

thanks
roland
