My Dell Optiplex 7040 with SSD worked fine with the 4.8 kernel. But after upgrading its firmware from 1.4.5 to either 1.5.4 or 1.5.7 I had the DRDY error at shutdown too. Kernels 4.4 and 4.9 shut down cleanly. Afer downgrading the firmware back to 1.4.5 kernel 4.8 shuts down cleanly again.
A similar problem is with our Optiplex 9020s (with hard disks). In the pool room that I upgraded to firmware A17 recently, kernel 4.8 shuts down with the DRDY error. Kernel 4.4 shuts down fine. In the pool room with the 9020s that have older firmware A07 or A12, kernel 4.8 shuts down fine too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1594023 Title: Poweroff or reboot hangs.
