At least all Fn + Keys worked. Now, since 2.6.21 it generally works but: When some Application is polling /proc/acpi/battery/*/state, the Fn - Keys (and perhaps the Lid-Button) became disfunctional until the next reboot. (Terminating the App didn't help) I can also produce the problem with a simple loop on cmd-line: while true; do cat /proc/acpi/battery/BAT0/state; done I figured out, that after system boot I can do a cat /proc/acpi/battery/BAT0/state for at least 3 times without breaking ibm_acpi. But then suddenly the keys FN - Keys are dead. greetings Andreas --=20 gnuPG keyid: 8C2BAF51 fingerprint: 28EE 8438 E688 D992 3661 C753 90B3 BAAA 8C2B AF51 --X1bOJ3K7DJ5YkBrT Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFGSE3SkLO6qowrr1ERAtt3AJ9gm42tRqCJ/15q/4lkf3GKCl1VZQCfSsEf xOIoBq8VtQnz0jUzQDrQnPg= =t7li -----END PGP SIGNATURE----- --X1bOJ3K7DJ5YkBrT--
