Yes. I attached this one. Meanwhile I tested with 4.0.9, too. I wasn't able to reproduce the problem with this kernel even after lots of reboots (the problem w/ 4.1 usually comes up during boot process (but not only - it can be seen after boot process, too)). The problem always is, that there are errors w/ one of the sata discs and at the same time, IO_PAGE_FAULT errors are rising as described before: [ 152.533708] ata3.00: failed command: READ FPDMA QUEUED [ 152.538102] ata3.00: failed command: READ FPDMA QUEUED [ 152.539862] ata3.00: failed command: READ FPDMA QUEUED [ 152.541778] ata3.00: failed command: WRITE FPDMA QUEUED [ 152.543861] ata3.00: failed command: WRITE FPDMA QUEUED [ 5818.068050] ata2.00: failed command: WRITE FPDMA QUEUED [ 5818.068059] ata2.00: failed command: WRITE FPDMA QUEUED I compared dmesg from 4.1 w/ 4.0 and I realized the following *missing* entries in 4.1: [ 0.000000] ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x01] lapic_id[0x01] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x02] lapic_id[0x02] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x03] lapic_id[0x03] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x04] lapic_id[0x04] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x05] lapic_id[0x05] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x06] lapic_id[0x06] enabled) [ 0.000000] ACPI: LAPIC (acpi_id[0x07] lapic_id[0x07] enabled) What does this mean? Is there missing some part of the acpi initialization? Thanks for any hint as Linux 4.1 is completely unusable here with these errors. Regards, Andreas
