2.6.22 x86_64 : kernel initial decompression hangs on vmware

Hi,
After upgrading kernel to 2.6.22 on a Vmware workstation guest version
5.5 and 6 , the kernel decompression stage ("Decompressing Linux...") is
hanging for a very long time (~5 minutes) before finally succeeding
(displaying "done.\nBooting the kernel.\n"). During this time, the VM
process is eating all the CPU time during the decompression, like an
infinite loop.
Between these 2 strings is the gunzip() function at
boot/compressed/misc.c which does the real job, and the problem seemed
to appear since commit 1ab60e0f72f71ec54831e525a3e1154f1c092408.
(2.6.22-rc1 hangs, 2.6.21.6 works). The problem occurs with or without
CONFIG_RELOCATABLE enabled.
What are the possible solutions to confirm where the problem is coming
from ?
Thanks,
Gabriel
