Description NiTr0 2010-04-18 16:45:42 UTC 
Subj. Kernel loaded with parameter acpi_osi="Linux" (without that eeepc-laptop didn't loaded).
Part of dmesg when I press wi-fi button twice:

FWIW, I don't see this on my 1001P, but I'm not booted with acpi_osi="Linux"

I shall try to reproduce that one of these days.
Comment 2 NiTr0 2010-05-16 12:47:01 UTC 
Without acpi_osi="Linux" eeepc-laptop module isn't loaded for me, and in this case I have troubles with brightness regulation and hotkeys.
Comment 3 Rolf Leggewie 2010-05-16 12:58:39 UTC 
I don't experience any problems with the Wifi hotkey even when booted with the acpi_osi option.
Comment 4 Rolf Leggewie 2010-05-16 12:59:38 UTC 
Try adding backlight=vendor as another boot option.
Comment 5 NiTr0 2010-05-27 12:52:49 UTC 
Without acpi_osi="Linux" on 2.6.33.2 I also have disabled eth0 instead of WiFi. And errors in syslog like these:
[   26.234386] ACPI Exception: AE_AML_PACKAGE_LIMIT, Index (000000010) is beyond end of object (20091214/exoparg2-445)

After upgrade to 2.6.34 - Wifi key doesn't work; manual disabling in /sys/class/rfkill/rfkill0/state also does nothing.
