Hi Tetsuo,
Is this bug reproducible ?
Does this oops happen while the vmware-install script is still
executing ?
Or does it happen after the installation/upgrade is complete ?
If its the latter case, Can you please determine what line in the perl
script is triggering this oops ?
The only thing that is clear from the oops is that the kernel state is
corrupted. None of the vmware modules are yet loaded in the kernel.
I would like to isolate the problem to see if this corruption is being
caused by any of the VMware modules.
Thanks,
Alok
