PS2 Touchpad Disconnects

[navjack27]

On my Gateway laptop model MS2274 I have Haiku's nighty installed. Sorry for being vague but somewhere between hrev56272 and hrev56297 a change was done that causes the PS2 touchpad to disconnect after being touched. I'll attach the current full syslogs. If you need me to I can go back to a known working version and then get the syslogs from that.

I suspected hrev56268 (PS2 keyboard reset changes) but that's just before the range you listed, so, if that range is correct, that's not it.

My next guess, but that is really a guess, is that hrev56274 (kernel/scheduler: Reset the invoke_scheduler flag on reschedule) allows for some race condition with the interrupts in the PS2 code somehow?

Oh and there's also hrev56293 which changed the touchpad code quite a lot, so that's more likely to be related.

i attached two new files. i used pkgman to sync to previous releases and found that 56295 is where the mouse has the disconnect bug introduced.

Ok so in the new log we can see this:

2570	KERN: Mouse device exiting, Operation timed out

Indeed it seems something did not work as expected with the move of movementmake to userspace in hrev56293. However I don't really see how this could happen by looking at the code?

Please retest after hrev56301.

hrev56301 works! No mouse issues. Awesome! Thank you.
