Re: [ath5k-devel] ath5k: phy0: failed to wakeup the MAC Chip
I have that model chip somewhere. Resuming works fine in freebsd. Is the MAC/PHY and PCI reset stuff correctly being (re) initialised after resume? What's in AR_SCR, AR_PCICFG, AR_RC ? 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.
