error state from that bsw but from _different_ run
(In reply to Mika Kuoppala from comment #5) > Created attachment 122771 [details] > error state from that bsw but from _different_ run Looks to be a simulated/stop-rings hang. Ville reworked the bsw irq handling to avoid lost interrupts, the root cause of this bug. |
