I have seen three instances of handler #02 > (NET_TX_SOFTIRQ?) over the past month or so while you are seeing handler > #08 (BLOCK_SOFTIRQ?), in case that makes a difference. Huch? #02 is TIMER_SOFTIRQ and #08 is NET_TX_SOFTIRQ. And looking at that ftrace output in the pastebin there is nothing which raises NET_TX_SOFTIRQ but then the warning claims it is pending. This does not make any sense at all. Thanks, tglx _______________________________________________ ath10k mailing list firstname.lastname@example.org http://lists.infradead.org/mailman/listinfo/ath10k
