Comment (by [EMAIL PROTECTED]):
As asked by kelmo in #1020, I follow up here with a description of the
problems
I have with r1819.
I'm running kernel 2.6.19-rc6 on a fedora 6 machine. The only non vanilla
driver
I use is madwifi and my setup is real simple: one physical device with a
single
station, without WEP/WPA.
With release 1819 my box hangs: not even sysrq works, nothing in the logs.
I can
trigger a hang by unscrewing the antenna.
I think (haven't verified) that it does an infinit loop in
ieee80211_iterate_dev_nodes because
of the change
{{{
- if (ni->ni_scangen != gen) {
[snip]
+ if (ni->ni_scangen) {
}}}
That's why I reverted this part of Tim's commit.
The other part I reverted addresses the clearly wrong
ieee80211_free_node(NULL)
call introduced by Tim's patch. Only reverting this is not enough to
resolve
my hangs.
