In my context somethings things go for weeks without this happening. I also have more trouble with such from debug kernel builds than from non-debug ones. I normally run non-debug kernels unless I'm trying to track down some issue. For non-debug kernels rebooting (shutdown -r now) does seem to initially clear the condition. This has been a fairly long term issue. >> 2.

For me both are related. I've seen this and, as I remember, it has been under debug kernels instead of non-debug ones. Since I normally run non-debug kernels, I normally do not see this. The powerpc's involved are still based on -r339076. The prior context with much use was long before that, predating -r334498 as well. I do not remember seeing this before the jump to -r339076 . So I expect this is somewhat new. I can not comment much on having smp disabled. The only time that I've had such was the jump to -r339076 until I identified reverting -r334498 as how to get back to a nearly historically-normal context. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
