Hi,
I tried to replace my broken atheros card with an ISL3880IK one but it
crashes. I tried both wireless-tools.28/29 and kernel 2.6.19.1/2.6.21.1
My system is OpenWrt on a Netgear WGT634U (mipsel).
Any ideas on that?
regards
Jan

Hi,
Any chance you could decode the oops ? If you're recompiling the
kernel yourself, include symbols (can't remember the option name), or
run ksymoops...

Sorry for the late reply ;) but anyway, I tried looking into this
finally (with new found knowledge on this subject, thanks to Kyle) and
I cannot see a place where isl38xx_trigger_device() would trigger
unaligned access.
Is this issue still present? If so I'd like to get to the bottom of
it. FYI p54 is there as a replacement but as you may know certain
features (ad-hoc, ap support, encryption) are still not present in
that driver.

Actually I've been informed this is not unaligned access problem but
instead it occurs on do_be() or ip22_be_interrupt() on MIPS. I'll have
to check how that works, I do not yet understand how this is reached.

"hardware encryption" does not work, since no one has implemented it.
but the software encryption is always available...
The AP Mode is a pain... Beause the firmware of the device changes the beacon
frames and does some accouting for the powersaving features...
There're workarounds, but they'll probably break something else.

Heh, wasn't expecting an answer anymore :)

Yep, I packaged p54 for OpenWrt and it's working for me. Well, I just
tried a scan and some APs showed up. But there was no segfaulting.
Hmmz, I wasn't aware that p54 doesn't support encryption or AP mode yet.
Is there any website/blog or something apart from linvilles commit log
where I can read about its progress?
Funny thing is, I had a chat with Michael Wu because p54 was segfaulting
for me. Turned out that I was missing some crypto modules, which are
only needed for encryption I guess. Therefore I assumed encryption is
working.

I will try a new build with prism54 in the next days and let you know if
that issue is still present.

Indeed, software encryption works like a charm (for me). This ISL3880
chip has a good range covered btw.

Sad to hear, but I guess there are many sad things to hear when talking
about wireless and open source.
How will AP Mode be realized once it's done? Via hostapd?

Well, it turned out that the mini-pci slot in the WGT634U was b0rked
after all and not the atheros card or the p54/prism54 driver :/
The p54 driver works fine on my x86 system, even with AP-mode. Thanks
for making this happen!
