Comment 6 for bug 1212160


This is a real oldie, but better late than never.

A while back, I discovered that this patch would help against a kernel
panic when "cat /proc/asound/card0/codec0" was executed on this machine,
which was running an fglrx driver.

I asked for a stable backport, but Takashi wanted testing to make sure
this was actually fixed by the patch [1]. And now, several months later,
I have this confirmation [2].

The test was conducted on an 3.5 Ubuntu kernel, based on the 3.5
extended stable tree, but would apply equally well to 3.4.

I'm attaching the backported patch - it applied cleanly, I've just added
an extra section with an explanation.
