>Description:
This computer works fine with 2.2.5 and I tried several times to upgrade it
to 3.0 and after the install when it reboots, it panics right
after the npx0 INT 16 interface line while booting. I reinstalled 2.2.6
current (980511) and it works fine again.
Here's the details after the crash and before the syncs:
Fatal trap 12 page fault while in kernel mode
fault virt addr 0x18

instruction pointer 0x8:0xf01fbbeb

>How-To-Repeat:
Try to install 3.0 on similar computer
>Fix:
Backdown to 2.2.6
