I need some help here, this is not a single case, I get this on a several=20
machines, this is releng_6 , recent, but old problem getting ugly
first I get this kind of events in messages, independent if it is client mo=
de=20
or hostap or adhoc
Dec 28 16:50:53 ap1-cds kernel: ath0: discard oversize frame (ether type 5e=
4=20
flags 3 len 1522 > max 1514)
Dec 28 16:51:01 ap1-cds kernel: ath0: discard oversize frame (ether type 5e=
4=20
flags 3 len 1522 > max 1514)
Dec 28 16:58:16 ap1-cds kernel: ath0: device timeout
=2E.. timeout event repeats=20
I really do not know what this event means (ether type 5e4), for my=20
understandings it is vague in the source, so I am lost here
{
I get continously:
kernel: ath0: link state changed to DOWN
kernel: ath0: link state changed to UP
when WL client but it recovers when the AP comes back to normal
so wl-cli mode is not the issue
}
but when the machine is running hostap the link state up/down events do not=
=20
come up but transmission is interrupted, or better, goes slow and stops=20
then - and stops forever until cold reboot, no chance to get this card back=
,=20
not even unload ath and reload the driver (that was a try but I use it=20
compiled into the kernel)=20
this is not related to any WEP settings or any rate, this problem is coming=
up=20
with either rate-sample or rate_onoe
this is not related to the "tx stopped" problem (OACTIVE) and it is not=20
related to any [TX|RX]BUF value (whatever it is set to)
this problem is not a single case and not hardware related, here I mean MB,=
=20
CPU, memory but is related in a certain way to the ath drv - same machine,=
=20
but wi0 (prism card) and it does NOT happen this way
I am with this problem since 6.0 and would be glad if somebody could convin=
ce=20
Mr. Sam L. to attend this since it is a serious issue - any FreeBSD releng=
_6=20
has this problem but releng_5 does not
depending on the amount of traffic I get this any hour ( when 2-3Mbit/s or=
=20
more) or several times a day (when 1-2Mbit/s)
it get worse when I have more then one ath card installed
