Title:
Madwifi (atheros) driver malfunction induces a system freeze
Status in linux-restricted-modules package in Ubuntu:
Won't Fix
Status in linux-restricted-modules source package in Intrepid:
Invalid
Bug description:
Hello
I have an extremely annoying situation that has developed recently. It
appears that the restricted atheros madwifi drivers :
$lsmod | grep "ath"
ath_rate_sample 14336 1
ath_pci 101024 0
wlan 207728 4 wlan_scan_sta,ath_rate_sample,ath_pci
ath_hal 192592 3 ath_rate_sample,ath_pci
are freezing the system. I am unable to find anything in the logs
except the following :
/var/log/messages :

There appears to be no corelation between a system freeze (display is
functional but all input - keyboard, mouse, tablet are all lit and dead - the
only way out is a hard reboot) and the uptime. Sometimes the system freezes
after hours of use, sometimes, its days, sometimes, its only 10 minutes.
The freeze appears to be more likely when there is more heavy network
activity.
This is a new problem - I have used this wireless card for more than a
year without any issues - these freezes started after I started using
the recent 2.6.2* kernels. Its a bug.
The problem manifests itself by onset of network problems - sometimes
the shoutcast stream I am listening to on amarok seizes up, then
korganizer loses connection to the calendar server, etc. The problems
appear to be intermittent, but a freeze follows sooner or later.
I am using Kubuntu KDE3 with NO desktop effects. I have an ATI card,
but please do not waste time telling me to disable desktop effects - I
do not use them (I have read plenty of bug reports in my efforts to
get rid of this so far to know that that is implicated sometimes).
