Summary: ath5k + 2.6.35 x86 + hostapd - Failed to set channel
Product: Networking
Version: 2.5
Kernel Version: 2.6.35
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Wireless
AssignedTo: networking_wireless at kernel-bugs.osdl.org
ReportedBy: nitr0 at seti.kr.ua
Regression: Yes
I decided to upgrade my router distro kernel from 2.6.32 to 2.6.35 - and
noticed that I loose wi-fi in it. hostapd reports:
nl80211: Failed to set channel (freq=2442): -518219808 (Unknown error
518219808)
On Gentoo box (x86_64) all works OK with Gentoo native binaries, and same
hostapd binary in 32bit mode with same libraries (checked by ldd - it pulls
libraries from building sandbox) with same card (DLink DWA-520) and same
hostapd config works perfect.
I tried to recompile kernel using config from Gentoo box (I just disabled here
KVM & DRI support, and of course changed CPU to PentiumII) - no effect. So it
looks that trouble is somewhere in kernel (it looks like stack
corruption/variable overflow). Channel is actually changed - iwconfig displays
that frequency changed.
Used compiler - GCC 3.3.3; binutils - 2.16.1; C library - uClibc 0.9.30.3
Kernel config is attached. After update kernel to 2.6.35.2 - nothing changes.
