Could you please load the driver with debugging (modprobe iwl4965 debug=0x43fff) to help us get a better idea what is going on. Also, if you can, can you determine on which line that GFP occurred? The error offset from above is 0xe1. $ nm iwl4965.ko | grep iwl4965_pci_probe Above will return start offset. Add the two numbers (start offset and error offset) and decode to file:line $addr2line -e iwl4965.ko <start offset + error offset> It is not clear which version of the code you are running, so when you send the line number please send it with some context so that we can find it if we are looking at another version of the driver.
