This bug was reported: https://bugzilla.kernel.org/show_bug.cgi?id=219508 The symptoms of this are that when there are a lot of writes to a mounted NFS share, especially through a VM or Docker, a soft lockup will occur. Based on the reverted commit this is because the assumptions made in the newer write code didn't account for a failed or short write. Ultimately this would cause an infinite loop where the NFS write never could release. The offending commit was here: https://github.com/torvalds/linux/commit/b571cfcb9dcac187c6d967987792d37cb0688610#diff- fc1b4de72479f94c3f3a9d6f626078f5392d88be93cfce08bb32883ac7a91a97L169 This was recently reverted: https://github.com/torvalds/linux/commit/66f9dac9077c9c063552e465212abeb8f97d28a7 This has been applied to the latest mainline 6.11.11 patch as well. This reversion was not included in the recent kernel release.
