AR_SCR = 0x4004 AR_PCICFG = 0x4010 AR_RC = 0x4000 -a On 25 March 2014 01:07, Eugene Shatokhin <eugene.shatok...@rosalab.ru> wrote: > Hi, > > On 01/21/2014 05:48 PM, Nick Kossifidis wrote: >> Since you have a version that works you could use git bisect to find >> out the patch that introduced the bug, try to revert it and see what >> happens. >> > > Well, our user that reported the problem first has not responded since I > sent him the first kernels needed to bisect the problem. > > Another our user, however, seems to have a very similar problem: the > system cannot wake up the WiFi adapter (Atheros AR2425) after suspend. > > This time, we could not find a kernel version where it works after > resume.
