Hi again,
  one of 2.4.x kernel images available in SuSE's 8.0 has patched&enabled 
support for page tables in high memory, and this quickly revealed
incompatibility between VMware's vmmon page table handling and
ptes above directly mapped range.

  So if you have >890MB of RAM and your kernel is compiled with support
for pte in high memory, please stop using VMware, or reconfigure your 
kernel to not use pte in high memory (4GB config without pte-in-highmem
is OK). Using pte-in-highmem with vmmon will cause kernel oopses and/or 
memory corruption :-(

  If you do not have >890MB of memory, then reason for your memory corruption
is still unknown to me.
