Hi Steven! Seeing as you were involved in: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=187594 I thought that you may interested to know that I´ve tested upgrading a virtual machine to 10.1-RELEASE with these patches applied: https://svnweb.freebsd.org/base?view=revision&revision=272875 And I can still hang a machine reliably just by adding a cache drive to the pool. Removing the cache makes it stable again. It´s not something new, this plague has been haunting us since 9.2-RELEASE and I would be so thankful if we could finally start using the cache drives with confidence again. I´ve filed a new bug, in case it´s not really the same issue as in 187594: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=197164 If there´s anything you need to test or whatever, I´m all for it, this VM is at your complete disposal. Best Regards Karli Sjöberg
