[2.6.12-rc2 - 2.6.12-rc5] oops with vmware

[Gabor MICSKO <gmicsko@szintezis.hu>]

Hi!

I have a problem with running vmware on between 2.6.12-rc2 and
2.6.12-rc5 kernels. I have no problem with 2.6.12-rc1.

Before running vmware:
------------------------------------

$ lsmod

With 2.6.12-rc1 vmware running perfectly.

Any idea? 

Thanks in advance.
