Re: [BUG] Kernel crashes with ath10k radio and Nexus 5X clients

["Timo Sigurdsson" <public_timo.s@silentcreek.de>]

Hi Mohammed,

so, I provoked the crash again on a newer build with debugging enabled
(LEDE r2321, Linux 4.4.32, ath10k firmware 10.2.4.70.54).

The relevant dmesg output is pasted below (with mac addresses
pseudo-anonymized). I hope this includes the information you were
looking for. If not, please let me know what other useful information I
can provide. I haven't rebooted the access point yet.

Regards,

Timo
