--- Begin Message ---Package: linux-image-4.9.0-0.bpo.1-amd64-unsigned Version: 4.9.2-2~bpo8+1 Severity: important Dear Debian folks, Apologies for the duplication, sending to the main submission list. After upgrading 3 Debian Jessie servers to kernel 4.9.2 from jessie-backports I encountered multiple kernel traces on 3 separate servers at random times after boot. As a result, one of the kworker processes and several user space pids are stuck in 'D' state and encounter issues accessing the XFS file system. A proper shutdown will not complete and a reset is required when this occurs. In one case this caused file system corruption and prevented the server from booting normally (dropped into a generic grub shell). No specific workflow to trigger these events (so far). The systems involved are: System Information Manufacturer: Supermicro Product Name: X9DRT System Information Manufacturer: Supermicro Product Name: X8DTT-H The example traces are as follows: [812709.892923] INFO: task kworker/u49:0:13127 blocked for more than 120 seconds.
