Low memory (64MB) causes PS/2 keyboard to stop functioning

[idefix]

When I boot hrev27578 with only one 64 MB memory module, the PS/2 keyboard doesn't respond to anything (e.g. numlock on/off, F12 doesn't work).
If I put in an 128 MB memory module (making it 192 MB), the keyboard does work normally.

See attached serial-logs for both scenarios.

Booting hrev27578 with 192MB: PS/2 keyboard does work.

Both logfiles contain "ps2: keyboard found", problem might be related to input server.

reassigning, not sure if you are the correct owner

dunno, I just checked with Qemu and 48MB and it worked OK. It seems the PS2 mouse fails to init. Could it be related ?

[idefix]

The PS/2 mouse fails to init because there's no PS/2 mouse connected to the computer. :)

I investigated this further:

• In VMware both keyboard and mouse work correct with 64MB.
• When I restart input_server (by killing it with Processcontroller), the keyboard starts working. Only this time my Wacom tablet doesn't work, but that's fixed by plugging the USB connector out and in. See attached serial-log.

Booting hrev27578 with 64MB: PS/2 keyboard doesn't work. After input_server restart keyboard works, but Wacom tabled doesn't work. Plugging USB connector out and in causes Wacom to work again.

With a recent release (e.g. hrev27964) not only does the keyboard not work, but "/bin/sh /boot/beos/system/boot/Bootscript" crashes. See attached serial-log.

Booting hrev27964 with 64MB: PS/2 keyboard doesn't work and "/bin/sh /boot/beos/system/boot/Bootscript" crashes.

Booted hrev28749 quite a few times (for bug #2531) and every time the keyboard worked perfectly (even when Haiku only got 44 MB to play with (MAX_TRACE_SIZE was set to 20 MB)).
"/bin/sh /boot/beos/system/boot/Bootscript" still does crash sometimes though.

[idefix]

With hrev30012, "/bin/sh /boot/beos/system/boot/Bootscript" doesn't crash anymore. (Keyboard also works perfectly.)

Instead, I get the following message in the serial-log: "runtime_loader: memory shortage in get_sorted_image_list()". See attached serial-log.

[idefix]

Booting hrev30012 with 64MB: PS/2 keyboard works, but "runtime_loader: memory shortage in get_sorted_image_list()" appeared in the serial-log.

I think this ticket can be closed:

• I don't have that computer anymore
• my laptop (also got 64MB) running hrev35349 doesn't show this behaviour

Thanks for the feedback
