ISL3880IK crashes with 2.6.19.1 / .21.1

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...

I recompiled the kernel with KALLSYMS and got this:

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.

Luis

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.

Luis

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.

"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.

Chr

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?

Thanks for looking into it, much appreciated.

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!

cheers
