I don't know the details, but I understood this only happens on CUS223. If someone has seen these cold reset problems on other boards, like XB140, I would be very keen to hear about it. > Anything we can do to help debug the problem with warm resets > failing to work properly in some cases? Thanks, but not right now there isn't anything. Once I have new ideas for the warm reset problems, I'll post them here. Testing those would be very useful. -- Kalle Valo _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
