[ath9k-devel] 3.14 Regression, kernel panic when suspend, looks ath9k / wireless related
Hi, since 3.14 I get an kernel panic when trying to suspend or hibernate (and in several other situations). Looks ath9k or wireless related, does not happen when I for test remove /lib/modules/3.14.1/kernel/net/wireless/ath* (also from initrd). Did not bisect yet, but could if needed.

To see this you can try: mcgrof@ergon ~/linux-stable (git::linux-3.14.y)$ git grep REGULATORY_COUNTRY_IE_IGNORE drivers/net/wireless/ That said, I'm happy to revert this as no driver is using it anyway. Folks who care for it can help fix this when they get the Fisher Price (TM) driver upstream. I however don't think however this is the issue though, this may be a timing issue and by reverting this commit you just so happen to not get it triggered. I'll Cc you on some series of fixes and if you can test one of those patches on top of v3.14.1 that'd be appreciated as an alternative. I'm also very curious to hear no one else would have run into the same regression as you have.
