ipw3945 troubles on feisty

[Matt Price]

hi,

running a mostly up to date feisty except for a custom kernel (2.6.19,
from ubuntu sources, has restricted-modules package installed,
workedfine till a few days ago), I'm having lots of trouble with my
ipw3945 wireless card.  I can still connect to networks but I lose the
connection more often than I usedto and my dmesg is littered with the
following:

[ 8599.288000] ipw3945: Error Reply type 0x00000005 cmd LEDS_CMD (0x48) seq 0x040A ser 0x004A0000

-------- 

...and so on.  the glidepoint issue may be separate -- my pointer works
poorly when ipw3945 is failing like this -- it may have to do with cpu
usage, which skyrockets under these conditions.  anyway I wondered
whether anyone else was seeing this issue and what folks had done to
fix it.  also where I should report this bug (though since I'm using my
own kernel I suppose the bug would be rejected).  

Thanks,

Matt
