Macrobug (M$) mouse hangs on sio1, using 'PS/2 -> serial' adapter; panics too when I disconnect the adapter.
>Description:
Sorry if this is a known problem - "FreeBSD.org"'s PR search doesn't work.
After removing all Serial ports ("sio*") from kernel, kernel panics after loading:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
[...]
Cause of the problem unknown yet
I tried to test the kernel without "sio*" coz someone told me that 'ep' NIC worked poorly ([dropped packets?], was slow, BAD pings, etc... I can get more info on this if needed) before 'sio's were added back to kernel.

>How-To-Repeat:
remove "sio*" from your kernel config, install new kernel, reboot [test NIC]
>Fix:
don't disable "sio*"?
