I am running Slackware64 15.0.  The kernels supplied by that distribution
are unmodified kernel.org kernels.

The patches will be reverted in Slackware as a matter of course when a
kernel.org "-stable" kernel with the fix is adopted.  Slackware does not
apply any patches to kernel.org kernels.  Nevertheless, I will raise a post
in the forum, hopefully later today.

Sure, will do.  I'll be able to get the dmesg log from my earlier tests and
config easily enough.  Testing with another kernel will have to wait until
next Thursday as that is when I'll next have physical access to the machine.

Which upstream kernel would you like me to test with: the latest "-stable",
or the most recent release?
