Never had a problem after an update, but after upgrading to 6.10, the boot process stop waiting for a device label UNRAID for 30 sec and stop saying UNRAID boot device not found, I revert back to 6.9.2 and everyhting runs fine on the same USB 2 drive without format, no change, just replace boot files with the backup files... I'm using a USB2 Lexar JumpDrive FireFly 4GB. Every plugins are up to date before the upgrade.
