Haiku wont respond if you boot it with mouse action

[diver]

Haiku wont respond if you boot it moving mouse around. When it boots, everything locks: time (seconds) in deskbar doesn't change, mouse doesn't work. If you stop to move your mouse, two seconds later haiku will alive.

This sounds like a problem of the PS/2 driver (probably a real time thread going nuts or some interrupt problem) - do you have any idea Marcus?

[marcusoverhagen]

I think it's more likely a problem of USB, please attach a syslog or serial debug log.

[marcusoverhagen]

Diver please attach a syslog or serial debug log.

I couldn't reproduce the behaviour and would like to close this bug.

[diver]

Ok, i could now reproduce it in vmware with hrev19802. Reopening, syslog will follow

Moving the mouse during boot does trigger sending (in this case) 13200 debug messages from interrupt context directly after the mouse is enabled, before the thread executing ps2_dev_command gets scheduled again and can set the enable flag.

The code responsible for that is:

	status = ps2_dev_command(dev, PS2_CMD_ENABLE, NULL, 0, NULL, 0);
	if (status < B_OK) {
		TRACE(("mouse_open(): cannot enable PS/2 mouse\n"));	
		goto err4;
	}
	atomic_or(&dev->flags, PS2_FLAG_ENABLED);

Please don't move the mouse during boot.

Replying to marcusoverhagen:

		goto err4;
	}
	atomic_or(&dev->flags, PS2_FLAG_ENABLED);

Please don't move the mouse during boot.

Can't we disable or at least reduce the debug output of the ps2 driver ? Or it's still too early to do that ?

[marcusoverhagen]

I'll disable the debug output of ps2

fixed in hrev20357
