>Environment:
System: FreeBSD pyanfar.ece.cmu.edu 4.8-STABLE FreeBSD 4.8-STABLE #4: Sun Aug 17 17:28:05 EDT 2003 allbery@pyanfar.ece.cmu.edu:/usr/src/sys/compile/TIRUN i386
>Description:
The emulators/vmware2 port does not work on recent -STABLE, failing
with "VMware Workstation PANIC: BUG F(571):1607 bugNr=2302". The
usual fix for this is to rebuild the kernel modules, but (a) they
do not build without patching and (b) the new kernel modules fail with
the same error.
No kernel messages were logged.
Update: retrying it with syslogd recording debug messages, the vmware
bugcheck no longer occurs, but vmware reports an inability to reserve
memory and the following is syslogged:

Aug 24 07:10:30 pyanfar /kernel: /dev/vmmon: PhysTrack_Cleanup: pfns still locked
>How-To-Repeat:
Attempt to boot a VMware virtual machine.
>Fix:
I used the following patch to get the modules to build; not being a
kernel hacker, I don't know if it's correct (and would guess it's not,
but have no idea what the correct fix is).
