maybe related to http://bugzilla.kernel.org/show_bug.cgi?id=9834 ?
you say "recent" , so this does happen from 2.6.21 to 2.6.26rc2 ?
does that happen only on a dedicated vmware box, or on different ones?
vmware-tools active? ->stop -> different ?
could you provide some more information about your hardware/vmware
environment ?
does that happen on esx or on hosted products (workstation, server,
player..) ?

I'm experiencing hang up problem with recent kernels in VMware environment.
Here are two examples.
http://I-love.SAKURA.ne.jp/tmp/messages.1 (203kB)
http://I-love.SAKURA.ne.jp/tmp/messages.2 (1.7MB)
The messages.1 is a log when "tar" stopped processing
while extracting a .tar.bz2 file by
"rpmbuild -bb --target i586 --with baseonly kernel.spec".
I got this log in runlevel 3 of Fedora 8.
The messages.2 is a log when the compiler processes (e.g. "cc1")
seem to be hanged up (no compiler messages appear for minutes,
which unlikely happen).
I got this log in runlevel 1 of Fedora 8
by "rpmbuild -bb --target i586 --with baseonly kernel.spec"
after starting rsyslog and stopping anacron.
I experience this problem in many distro (e.g. Fedora, Ubuntu, SuSE),
which use kenel (I think) around 2.6.21 and later.
I experience this problem only in VMware.
I have never experienced this problem in native environment.
I experience this problem only when I assign 2 CPUs to VMware.
I have never experienced this problem with 1 CPU.
May be something scheduler related in SMP + VMware environment.
The a.out process in the log files are http://lkml.org/lkml/2008/5/12/130
What other information should I dump for identifying the location of hang
up?
Regards.
