Hi, I have just upgraded to 2.6.38 and discovered that I can't use my wireless device (BCM4312 802.11a/b/g). I press Fn + F2, the bluetooth led lights and after a second it turns off by itself. In dmesg I'm seeing the following: [ 88.167212] usb 1-2.2: new full speed USB device using ehci_hcd and address 5 [ 88.782330] usb 1-2.2: USB disconnect, address 5 I switched to 2.6.37 until I'll have some time to bisect this. In the mean time I have attached the output of lspci, interrupts and dmesg.
I suspect it's WMI related. What is your machine? Please check: https://bugzilla.kernel.org/show_bug.cgi?id=31002 http://comments.gmane.org/gmane.linux.acpi.devel/49577 I can't help you more, I just noticed such a issue reported on ACPI ML, you have to dig into this yourself (or someone else may help you). -- Rafał
