System panic after running "ps2republish" from KDL

[luxohaiku]

When i started Haiku beta 4 (The installer from a DVD) i noticed that both the keyboard and the trackpad were not working, so i connected an external USB keyboard and i went in the Kernel Debugging Land. Tried to run some commands to see if i could find any hints on what could be causing the issue. As soon as i run the "ps2republish" command the system panicked. The laptop i used to run Haiku is an HP Compaq 6720s.

Ouput of the panic

What about a nightly build?

Even with a nightly build the keyboard and trackpad aren't working, and using "ps2republish" from KDL produces a panic.

Panic in the nightly build

You have uncovered a 15-year-old bug.

The command admits a device number, "(0-3 mouse, 4 keyb (default))". Unfortunately, after hrev28416(!), the keyboard is number 5 and the default 4 is synaptics passthrough, which passes commands to parent device, which in this case is not set and nowhere is that checked.

Please check with hrev57770 or newer.

Tried it with "hrev57774", now using the "ps2republish" command doesn't produce a panic anymore.

Thanks for the feedback. About the non-working keyboard device, is it a ps2 device?

[luxohaiku]

Both the internal keyboard and the internal touchpad are recognised as PS/2 devices.
