In most cases, the com lock = was obtained before the driver lock; however, there were multiple ieee80211_cancel_scan() calls (from rt2560_start, rt2560_newstate), where t= he driver lock was taken before the call - and that results in LOR because ieee80211_cancel_scan() takes com lock inside. The issue was fixed in base r178354 - cancel_scan() calls from rt2560_start were dropped and rt2560_newstate is now called under com lock (and never ca= lled directly from the driver code). --=20 You are receiving this mail because: You are the assignee for the bug.=
