Hi Larry - Thanks for the patches. I've applied them to bugs #197959 and
#192720 (plus the debug config patch). I'll get a test kernel built and
solicit some feedback in the bug reports before I go through the SRU
process. As soon as I have a PPA kernel built I'll advertise it at

Hopefully we can get some feedback from der_vegi and figure out if there
is still a regression.
