PS/2 keyboard and touchpad not working on cold boots

[mmlr]

When cold booting my laptop (hp2510p) directly into Haiku the keyboard and touchpad are not working. If I reboot from BeOS or if I first boot into Haiku with safemode (consoled only - keyboard works there) and then reboot from there, the keyboard and touchpad work fine. This has been the case since I got that laptop and first installed Haiku, but hasn't been so urgent as I usually reboot into Haiku. Last tested with hrev25862. I enabled TRACE_PS2 in ps2_common.h and booted two times, once cold and once rebooting from BeOS. Attaching syslogs from both runs. They are a bit truncated, but I think all the relevant infos should be in as "ps2_hid: init_hardware" comes directly after the truncation.

I think there is a problem with the BIOS emulation of the PS2 controller. In case of cold boot, it doesn't seem to be in the correct state, and doesn't behave properly.

cold boot logfile:

1308	KERN: ps2: active multiplexing not supported
[...]
1352	KERN: ps2: ps2_dev_command wait for ack res 0x80000009, wait-time 4001009
1353	KERN: ps2: ps2_dev_command result 0x80000009
1354	KERN: ps2: reset mouse failed
1355	KERN: ps2: probe_mouse reset failed
1356	KERN: ps2: probing mouse input/mouse/ps2/0 failed

warm boot logfile:

1321	KERN: ps2: active multiplexing v1.1 enabled
[...]
1362	KERN: ps2: ps2_dev_command wait for input res 0x00000000, wait-time 326018
1363	KERN: ps2: ps2_dev_command rx: 0xaa
1364	KERN: ps2: ps2_dev_command rx: 0x00
1365	KERN: ps2: ps2_dev_command result 0x00000000
1366	KERN: ps2: reset mouse success

Please attach a logfile of a cold boot without USB drivers and without any external USB devices or docking station attached.

It's either a problem of USB legacy emulation not properly entering the "USB extrinsic support with keyboard controller" mode (see page 11 of the usb_le9 pdf), or the bios is expecting some PS2 commands (that we don't send yet) before it enters a functioning state.

This has been resolved in the meantime. The laptop is now pretty much fully working except for wlan. Going to close this as fixed even though I have no real idea when or what would've changed it.
