[gentoo-user] kernel panics after 'ifconfig wlan0 up'

[gentoo-user] kernel panics after 'ifconfig wlan0 up'

[Maxim Wexler]

Hi group,

Emergency here. After my eee pc boots I log in and enter '#ifconfig
wlan0 up' as usual to take advantage of the free wifi at the coffee
shop. Then, just before I enter the next command, the kernel panics
and the console freezes. The top line of hexidecimal barf reads:

ath5k_tasklet_rx40x1fd/0539[ath5k]

and ends with:

Kernel panic -- not syncing: fatal exception in interrupt

I'm wracking my brains trying to figure out what I did or neglected to
do prior to this but am drawing a blank.

Running 2.6.29-r5. Never had this problem before. '$cat
/proc/acpi/net/wireless' indicates that wlan0 is configured.

Anybody have any ideas?

Maxim

Maybe you can try to use newer drivers; if you don't want to update
the entire kernel you can build just the latest wireless drivers from:

ok, found it. On the sixth I did #make menuconfig && make
modules_install and rebooted without any problem, everything worked as
before. But I neglected to copy over the new kernel. All the fresh
modules seeemed to get along fine with the stale kernel for an entire
week so it never occured to me there was a problem till I tried to go
mobile and the wifi module gagged. I wonder why that one was singled
out.

So, crisis passed. Well, until I go mobile again and try to connect.

Thanks for your interest
