| |
Hello,
I'm using Debian lenny (linux 2.6.26) and I have a iwl3945 wireless card. My laptop is a lenovo r61i. I've notice that, when I turn off the wireles/bluetooth switch the wireless module isn't removed, the kernel even displays a few warnings:
% dmesg | tail -n11 [ 1219.735652] iwl3945: Radio Frequency Kill Switch is On: [ 1219.735652] Kill switch must be turned off for wireless networking to work. [ 1219.787767] usb 1-1: USB disconnect, address 2 [ 1221.291865] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC [ 1221.294246] iwl3945: MAC is in deep sleep! [ 1221.341983] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC [ 1221.345953] iwl3945: MAC is in deep sleep! [ 1221.405968] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC [ 1221.450835] iwl3945: MAC is in deep sleep! [ 1221.612230] iwl3945: WARNING: Requesting MAC access during RFKILL wakes up NIC [ 1221.632612] ACPI: PCI interrupt for device 0000:03:00.0 disabled
So, when I turn the switch back on, my wireless card is not operational. I have to manually remove and then reinstall the iwl3945 module in order to the device to resume working. The bluetooth device doesn't have that issue.
Is that an expected behaviour? Would it be impossible or undesirable to the kernel to behave differently? Is it already fixed in the newest kernel version (or on the -mm branch)? I am willing to hack into the kernel code in order to fix that problem, if someone would give me pointers of where to start.
