Sorry for being slow to get back to this. Here's dmesg from the first "blocked" message, this time including a sysrq-w dump at the end. This is Chuck's for-next (bb49f295d682, which is based on 6.0-rc3). The client is hung in generic/590 with "server not responding, still trying" messages. For what it's worth, the server is a VM, and the exported xfs filesystem is on a virtio disk (which in turn is backed by a file on an xfs filesystem on an ssd). The host seems to be behaving normally. --b. [ 5438.560575] INFO: task nfsd:23105 blocked for more than 120 seconds.
