Colleagues, one of our machines does *not* work properly with ATA tags even after last splx commit to ata-all.c. The only difference I've found with it is that it has three IBM disks and one of them does not support tagging: Jun 20 18:44:40 jubjub /kernel: ad0: 19574MB <IBM-DPTA-372050> [39770/16/63] at ata0-master tagged UDMA33 Jun 20 18:44:40 jubjub /kernel: ad2: 9641MB <IBM-DTTA-371010> [19590/16/63] at ata1-master UDMA33 Jun 20 18:44:40 jubjub /kernel: ad3: 58644MB <IBM-DTLA-307060> [119150/16/63] at ata1-slave tagged UDMA33 so, as you can see, there is tagged-capable disk at ata0 and two, one capable and one non-capable at ata1. Troubles I have look familiar: Jun 20 18:44:40 jubjub /kernel: ad3: READ command timeout tag=0 serv=0 - resetting Jun 20 18:44:40 jubjub /kernel: ad3: invalidating queued requests Jun 20 18:44:40 jubjub /kernel: ata1: resetting devices .. ad3: invalidating queued requests Jun 20 18:44:40 jubjub /kernel: done Jun 20 18:44:40 jubjub /kernel: ad3: no request for tag=0 Jun 20 18:44:40 jubjub /kernel: ad3: invalidating queued requests Jun 20 18:44:40 jubjub /kernel: ad3: READ command timeout tag=0 serv=0 - resetting However, this machine locks up instead of just dropping to PIO (and cause it's production machine, I had not much time for experiments) I can provide more details if you are interested, Soeren. Anyway, thank you again for you work at ata driver.
