Subject: [386bsd] Dell keyboard problem
Lines: 17

I have 386bsd 0.1 running on a Dell 486D/33.  It seems that the 386bsd
keyboard handler leaves the keyboard controller in a funny state,
since when I reboot with "shutdown -r", the BIOS reports a keyboard
error on the way back up, and when the system is running again, the
keyboard doesn't work anymore. - I have to power-cycle to get it back.
My guess is that 386bsd puts the keyboard into an unusual state for
its own purposes, and rebooting from software doesn't do a complete
reset of the whole system.  Anyone seen this before?  Anyone have a
patch?

While I'm here, isn't there a better way of rebooting the system than
zorching the page tables?  I know that this causes a triple fault,
which makes the CPU shut down (which causes a reboot on an ISA bus
machine), but it seems to me to be a rather barbaric way of doing
it....
