I have similar symptoms, on a Dual AMD64, 4x SATA GELI + RAIDZ. Mainly after I turned off one drive out of 4 in a RAIDZ pool (one of the two SATA channel on the motherboard is flaky, I'm waiting for a new PCI controller) and I can consistently reproduce it mdconfig-uring a 120GB image of a ddrescue-d HDD and then mounting an UFS2 partition on it and moving massive amounts of data in that hangs within few minutes, but it will lock after a few hours anyways even not touching that huge file. I'll try to produce some debugging myself ASAP... Lapo
