Interesting, the TX code did change for 2.6.27 recently with the DMA changes
by GertJan, I think the Fedora kernels which are showing the above panics already
contain those patches,

John, Does Fedora kernel 2.6.25.10-86.fc9.x86_64 contain rt2x00 2.1.8?

I also have some reports about a queue corruption in rt61pci and although I haven't
figured out how that corruption is caused, I do think the above panics might somehow
be related.

Thanks for the report,

Ivo
