I'm quite puzzled with the above printout. So either there's some weird regression either in driver or the pci subsystem. It's good you posted ;-) Just to be clear: were you using 4.2-rc3 as in from Linus' tree or Kalle's tree? Asking for a `git bisect` is probably a bit excessive - but it would help a lot. I guess you'd have to manually cherry-pick qca6174 hw2 fix [1] while bisecting. If bisect is too much I guess you could try reverting (in order): https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/ath/ath10k?id=0bcbbe679b66fee1b56def5cb30bfb4f616b1127 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/ath/ath10k?id=76d870ed09ab34154454b1adb823ae75f173c2d2 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/ath/ath10k?id=77258d409ce45890104e3da11d0261402c49aee1 I'm shooting blind here though. > [1] https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/drivers/net/wireless/ath/ath10k/pci.c?id=11a002efbaa7fbd9f6e616695ab42aa9f1caf060 Michał -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
