Hi everyone,
i hope this is the correct place for reporting Kernel-panics on (ubuntu) systems using Linux 3.x and rt2800pci.

Me (and many other) ubuntu-users are facing issues with different
Version of Kernel 3.x. As it seems all users are using "rt2800pci" for
there wifi.

As it seems, the panics are happening more often, when on battery.

Also, this bug never happened on 2.6.38-x, Just with 3.x

My initial bug-report can be found here

Here is a quick summary about the panics

Just my guess about the problem:

https://bugs.launchpad.net/ubuntu/+sour ... omments/94

But because i am not sure, maybe someone of you have some usefull informations. I will also do some testing with other firmwares.

I'm using compat-wireless-3.2-rc1-1 on an embedded ARM9 processor and also getting frequent kernel panics using the rt73usb driver.

just for the recod. Changing the firmware rt2860.bin does not solve the problem

That makes sense. Did you know that Ralink's firmware was updated by this commit?

Below is the correct md5sum for the correct version of rt2860.bin.


The above firmware is the one that comes with Oneiric.

Having said that have you tried the latest version of compat-wireless?

The reason I as is because I noticed that today a patch was submitted to hopefully fixz rt2800pci devices.

In the end I will say I am not a Ralink dev... just a user... I just like to keep track of bug reports and patches as they come in.

Having said that I have the dreaded rt3572 (ae1000) working great in Lucid using compat-wireless-3.2-rc1-1 and the latest firmware from the commit above.

I may be having better success with compat-wireless-3.2-rc1-1 as well, though it's still too soon to tell. Not sure if I'm even experiencing the same problem, but I did notice 3.2-rc1-1 includes a kernel module for eeprom_93cx6 (IIRC).

jawilljr, thank you for your feedback and the usefull informations.

I have taken the kernel-patch and making a new kernel from it for ubuntu (i386) to provide a kernel for further testing.

Hopefully this will fix the issue
