Hi Sebastian, Thank you so much for pointing out PREEMPT_AUTO, I read the discussions last weekend, glad to know PREEMPT_AUTO. And riscv has switched to generic entry, so it's easy to support PREEMPT_AUTO for riscv. V2 was sent out a few mintues ago. Could you please review? > > Are there any reports of this booting without warnings with LOCKDEP and > CONFIG_DEBUG_ATOMIC_SLEEP enabled? I remember there was something > earlier. IIRC, Conor reported the warning and stack trace is ext4 related. But I didn't reproduce the warning. And Schaffner also tried the series but it seems he didn't see the warning either. So I'm asking for Conor's help to retry v2.
