hello Jussi, I'm the natty user that filed the initial bug report; have been asked by Fabio to contact this site directly . here below the results of proposed patch apply procedure ----- hello Fabio, I tried several ways ie the enclosed code stripped - just starting with diff -- etc, etc AND with all explanation ie zd1211rw: etc, etc. results root@GIGA-slow-1104:/home/peter# patch -p1 < zd1211rw-kpatch patching file drivers/net/wireless/zd1211rw/zd_mac.c Hunk #1 FAILED at 160.

The patch in question is queued for 3.1. You can test it by building the wireless-next-2.6 tree: git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next-2.6.git Please try that and give feedback here. Alternatively, you will have to wait until the 3.1 kernel is released (in 4+ months).
