IPv6 uptake suffers, 802.11g on the rise (and fall, about 2.4 thousand million times per second)

Well, the good news is that I got my wireless working with the latest dscape stack…

Up until now, any dscape stack more recent than the 060102 drop would bug when bcm43xx tried to send a packet. The stacktrace looked something like this:

Vector: 300 pc=e2157440: iee80211_master_start_xmit + 0x6c/0x4bc [80211]
            lr=e2157400: iee80211_master_start_xmit + 0x2c/0x4bc [80211]
msr 9032 sp df853d70 [df853cc0] dar -08 dsisr = 40000000

Anyway, today I decided to actually track this down. Must be all the PowerPC presentations I keep going to…

First try was that low-hanging fruit, Ipv6. It gets dragged in somewhere during the boot process, despite not being listed in /etc/modules. Luckily, the easy solution is the rename the module, so modprobe can’t find it. ^_^

And lo and behold, the dang thing worked!

So I finished off the dscape-based packages I based on rene’s softmac-based packages and uploaded it to http://www.tbble.net/dscape/

So LCA report for today will be late, since I’m currently at the Perl BOF and will have to dash off to the Penguin Dinner after.
