[Bug 1349108] Re: Disconnections problems each day after upgrade linux-firmware:amd64 (1.127.4, 1.127.5)

  Thread Previous • Date Previous • • Thread Next 
I'd call that more of a workaround than a solution. It seems apparent
that there is some firmware aspect to the problems, but from others with
similar problems it sounds like it's at least less prevalent with 3.15
and 3.16 kernels.

I've identified a couple of fixes that could be responsible for the
improved behavior, and I've made a test build for trusty with these
fixes. I'd appreciate it if you could give it a try (with the -8
firmware) and let me know how it works for you. I've posted the build
at:

http://people.canonical.com/~sforshee/lp1349572/linux-3.13.0-32.57+lp1349572v201408111147/

Thanks!
