i installed Fedora 15 on my Lenovo G475 notebook, which has a Atheros AR9285 wireless adapter. if i turn on the wireless card in my bios, my system hangs after boot everytime. then i disable the wireless, my system works well. i've tried different kernel, eg. 188.8.131.52, 184.108.40.206, 220.127.116.11, all of them have the same problem.
i've report the bug to Redhat, but it seems that they cann't solve it.
and i've tried the methods which are described on debian and archlinux bug lists.
but the problem still there...
another thread, maybe the same problem...
Possibly related too:
There is also patch-workoround available:
mine is FC15, so i cannot use your srpm or rpm directory. i downloaded the
patch you told us and the compat-wireless-2010-08-21.tar.gz which is stable
enough as pepole on the archlinux buzilla said.
i patched the compat-wireless source and made some small changes, and then i
build the modules for my 18.104.22.168-30.fc15.x86_64 kernel.
i installed the modules and enabled my ar9285 card again, so far, it works
my patch for FC15:
if i start my notebook for the first time after completely poweroff,
although i've using my patched compat-wireless 'compat-wireless-2010-08-21',
the system still hangs... if i reboot into my WinXP, then reboot to FC15, the
system will not freeze. very strange! so the problem do not completely resolve.
