BTW, I see another LOR with spinlocks, maybe harmless. o sysbeep() is called from syscons code and it calls timeout() which introduces the following order: scrlock -> callout.
o The callout code programming of event timers introduces the following order (via callout_new_inserted == cpu_new_callout): callout -> et_hw_mtx o Eventtimers' doconfigtimer calls loadtimer with et_hw_mtx held, loadtimer calls et_start method of a configured event timer and, e.g. in the case of lapic_et_start and bootverbose it calls printf(9), which gives: et_hw_mtx -> scrlock This is just for the information. -- Andriy Gapon _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
