We're having the same issues & running "mfiutil show volumes" every minute doesn't make the freezes go away. > Will this small patch be ok on 8.2-RELEASE-p4? Thanks. I'm about to commit a major patch to mfi, which many problems with the current driver. Given info in that PR it could well fix this problem. Unfortunately due to the number of changes, its likely to sit in head for a while before it gets MFC, just to be safe. We've been running it on 8.3-RELEASE on top of the driver from head for some months and not issues so far. So if anyone is interested in a patchset for that I'll be able to provide. I'll post a link to the commit when I'm done.
