• Product: Gentoo Linux

[Description Alex Ermakov 2010-04-15 21:02:44 UTC]

Intel WiFi adapter on my Asus EEE PC 1005HAG doesn't work under 2.6.33-gentoo-r1 kernel. rfkill reports that adapter in hard blocked state:

0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes

When i boot with 2.6.31-gentoo-r6 kernel there is no such problem and WiFi works fine. rfkill output:

0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: eeepc-wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: eeepc-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Reproducible: Always

Steps to Reproduce:
1. emerge =sys-kernel/gentoo-sources-2.6.33-r1
2. Boot with installed kernel
3. Look at the rfkill list output

Actual Results:  
WiFi doesn't work.

Please test with acpi_osi=Linux added to kernel parameters

Thank you. Now WiFi works fine.

Ok, great. Closing as workaround has been identified until upstream provides proper fix in new driver.
