Description

versions <= madwifi-ng-r1447, drivers compilated as modules for kernel 2.4.x for xscale BE (ixp425) are running

After vertion r1451 until version r1637, i obtain a kernel oops

here is logs with madwifi 0.9.0 stable

Thanks for the report. Please check DevDocs/KernelOops to learn about how to "decode" the kernel oops. The opaque pointers that are contained in the oops you've pasted above are of no help, and decoding them to something more useful is required in order to be able to find the cause of the problem you're facing.

Kernel 2.4.x, Rel 0.9.1 crash happens inside ath_hal_attach() as described above. r1447 (old hal) works Ok. See ticket #617. Does anybody have a patch?

Hello,

I think this is IXP425 specific. I did attachment as patch-ah_osdep.txt. I confirmed it by kernel2.4. I believe that the patch will be useful not only kernel2.4 but also kenel2.6.

08/30/06 23:51:28 changed by ediment@veyu.com

That worked for me. Taku, thank you!

  • patch_attached set to 1.

The patch would need a review by one of our devs (I think of Pavel), but it seems to be ok. However, in order to be able to commit it to the repository it needs to be signed off. Taku, can you please do that?

Here is what I think we should be doing. {read,write}l have been ported to all architectures by the Linux kernel architecture proters anyway; no point in us reproducing the effort.

  • milestone set to version 0.9.3.

That - and the things you told me on IRC (basically: available in all kernel versions we support, no known side effects) - makes sense, and the proposed patch (madwifi.pci-register.diff) looks good. Feel free to commit at will.

Please try again with latest subversion. There were a few issues with licensing, which have been sorted. There was also some issue with iomem types, but that is fixed now too (I hope).

Even if you don't have ksymoops on the target, you could gather the relevant information and feed that into ksymoops on another machine. Refer to ksymoops(8) for details, then please provide a fully decoded oops dump. DevDocs/KernelOops might also be of help.

  • status changed from new to closed.
  • resolution set to fixed.

Originally reported issue seems to have been fixed by r1716, r1726 and r1729. It's unsure if the oops that has been reported by d.baker is actually related to this ticket (since the oops is not yet provided decoded).

I close this ticket as "fixed". If the originally reported issue still shows up, feel free to reopen this ticket.

@d.baker: In case you can provide a decoded oops dump, please open a new ticket for your issue. Thanks.

I get an kernel oops similar as d.baker@mchsi.com has. The build is the latest(r1885) I am running uclinux 2.4.31-uc0 @IXP425 BE

My board is able to run madwifi-old without any problem, but when I move to madwifi-ng, haven't get any luck with mulitple revisions. Any help is highly appreciated.

Thanks!

Hi, vincent

Plase try to remove "-march=armv4" option from "COPTS+" in "hal/public/xscale-be-elf.inc" file.

I belive that it will fix this compile error.
