Very strange behavior of the special keys on a IBM T40

[a***@rfc2549.org]

Hi,

I have very strange and annoying problem with my T40. Whenever I press
some "special keys" like volume up/down brightness up/down, Thinklight
on/off FreeBSD just freezes.
This is with a current kernel.

Anyone any suggestion what I could do to narrow this down?

You could try to check these keys with ports/x11/xbindkeys .


With kind regards,

Would you by any chance be running with an extra ultra bay battery in

place on

the CD/DVD? If so, try removing it (and rebooting). If you're having

the same

problem I have on my T40p, that should eliminate the hangs. As a

result I'm

almost never using the extra battery :(

I have a extra ultra bay battery but I makes no difference. :/
Could you send me your kernel config, maybe I have something weird in
my config?

Okay, I tried your kernel config but the same result brightness
up/down freezes the kernel.
Without acpi the kernel freezes after something like 1-2 minutes :(

Well, I "narrowed" it down, my notebook is now *real* crazy, even with
a 5.2.1 kernel (which worked :/) it now shows this behavior. I have
now absoluty no idea what I could try next :/

I've had exactly the same problem with my X31,
the solution that worked for me was to disable 'IDE2' with the 'PS' utility
that can be found on
IBM's site.(nasty DOS based, boot floppy image, that gives you advanced
options not available in the BIOS)
After this everything woks perfectly, i can turn up/down the volume and use
the keyboard light.

I hope that this info will help you.

Sorry about the late response, but it seems you found my config anyway.

I have never experienced any kind of 'delayed' freeze effects though. If it
feezes it has always done so immediately.
