[madwifi] System Freezes on me randomly

[esac]

I am running Breezy. I am updated as of now. With both the 2.6.12-8 and now
2.6.12-9 kernel my system will randomly freeze on me. The mouse stops working,
the display stays there, but doesn't update, keyboard commands aren't
recognized. It is a hard hang. There is nothing that seems to be consistent
when it happens. It's not always the same programs or same actions I am doing.
 I do have VMWARE 5.0 workstation installed, using the any2any installation
method (patch), but it isn't always running (except for the vmnet drivers).

I have asked numerous times in the #ubuntu freenode channel for instructions on
what to do to help to get this resolved. Should I run a debug enabled kernel? Is
there some tracing I can turn on? How can I help? I am afraid that this issue
will still exist when breezy gets released. Let me know how I can help you.

You can start with https://wiki.ubuntu.com/DebuggingSystemCrash

Also try running without any VMWare drivers or other third-party code and check
whether the crash still occurs.

Attach your /var/log/dmesg

dmesg output

this is my dmesg output as requested. This is while the system is running
(obviously) but will continue to use my computer until it freezes again.

This repros after uninstalling vmware completely. I also downloaded the
2.6.13.2 kernel (compiled myself) and it repros with this kernel as well.

Also noting that I ran memtest, and had 0 errors.

Ok. I've narrowed it down. I found a 100% repro by trying to play a video from a
remote system on my LAN. I found this out after installing gentoo, so I knew the
issue wasn't distribution specific. The issue turns out to be with the madwifi
driver. I installed ndiswrapper and it works without any problems, so please
resolve this bug to madwifi maintainers.

Also on a side note, I also tried the madwifi driver snapshot 20050925 and it
still repro'd.

Thanks

Did you try disabling laptop-mode? This sounds to me a duplicate to

We are closing this bug report as it concerns the 2.6.12 kernel from Breezy which is no longer supported. However, please reopen it if it is still an issue with a supported version of Ubuntu and feel free to submit bug reports in the future.
