serious problem with 5.3-B7 and linux emulated vmware

Hi all,

in the first place, i had some issues, that i've also posted in 
-emulation, but now i have found out a critical problem with 5.3-BETA7.
I installed vmware3 from /usr/ports/emulation/vmware3 as supposted. 
After i turned on the first time a vmware session, my mouse in X almost 
freeze, console has delayed input, and top believes that all %CPU 
activity is at 0.0.

But my biggest concern is, that my ATAPI Controller "crashes" unusable:

acd0: FAILURE - ATAPI_IDENTIFY timed out

when i try afterwards to use an ATA device, in this case the cdrom. 
(e.g. just starting /stand/systinstall, and it hangs with that error)

But it got a bit better. One error is missing since BETA6:

watchdog: xl0 timed out

In 5.3-B6 in the same moment, after starting a vmware session, as soon 
the secound networkcard had activity, *all* networkcard got stalled with 
the watchdog timeout message. With the latest B7 i could not reproduce 
this anymore (yet).

I have tried all ways out, with no SMP, and no ACPI, linux_base or 
linuxbase-8 ,vmware2 (patches from -current) or vmware3 and so on... 
everytime it is the same effect after i did turn on once a vmware session.
I have seen another one, that had an IDE disk, that was inaccessable 
after he turned on the session. I do not have a normal IDE disk attached 
on the system. I got an Adaptec Raid Controller, so thats way got much 
far than him. And losing the access to the fixed disk, i would count as 
an critical bug.

In FreeBSD 4.10 everything runs just fine. So i believe there are still 
some serious bugs in 5.3. And since it wants to become "stable", i would 
like to help with any information that i can give, to solve this prob, 
since in that case, a Linux-prog was able to totaly "crash" the mashine 
into an unusable state.
