Hi, We get repeatable panics on a old machine, where a ATA disk seems to have problems. It works fine on 4.4 (beside some timeout messages), panics reproducable at startup every time at the same place. With 4.4 we got: ad0: READ command timeout tag=0 serv=0 - resetting ata0: resetting devices .. done ad0: READ command timeout tag=0 serv=0 - resetting ata0: resetting devices .. done ad0: READ command timeout tag=0 serv=0 - resetting ata0: resetting devices .. done ad0: READ command timeout tag=0 serv=0 - resetting ad0: trying fallback to PIO mode ata0: resetting devices .. done Everything worked. Now, after a upgrade to 4.6 STABLE we get a panic after "ad0: trying fallback to PIO mode". Set the device in BIOS to PIO mode doesn't help too. Unfortunatly it's the root disk ... I'll try now to make a DEBUG kernel and to get an usable dump.
