Now I followed your advise and found out the following (source from some ho=
urs=20
ago, 4BSD scheduler, and the acpidump went away to you by private mail)
The panic only occurs if the nvidia.ko module is was loaded.
I use it straight from the ports.
But your sysctl tweak keeps the whole thing working (I'm writing with kmail=
)!

Hope this helps (anyway, this driver is absolutle mandatory for my=20
workstation!)

Thanks,
