** Summary changed: - ata timeout exception with linux 2.6.28-11 + ata timeout exception with ahci libata driver (was with 2.6.28-11, but i confirmed it affewcts previous kernels too)
** Description changed: Binary package hint: linux-image-2.6.28-11-generic package: linux-image-2.6.28-11 release: Jaunty Beta latest version tested: 2.6.28-11.38 Trying to boot the new 2.6.28-11 kernel on Jaunty Beta results in many ata timeout errors (like the one copied below) that make the system unusable. Sounds much more serious than https://bugs.launchpad.net/ubuntu/+source/linux/+bug/343919, and different, in as much as it is not an ext4 fs that I am aware of, it is not an nvidia disk controller, and these errors are many more than ~10, and trivially easy to reproduce (it happens every time, from the first disk-reads onward) dmesg error message: [ 75.816051] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [ 75.816135] ata1.00: cmd ca/00:10:50:27:1e/00:00:00:00:00/e9 tag 0 dma 8192 out [ 75.816137] res 40/00:00:00:00:00/00:00:00:00:00/00 Emask 0x4 (timeout) [ 75.816275] ata1.00: status: { DRDY } [ 75.816337] ata1: hard resetting link [ 76.804036] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [ 76.806704] ata1.00: configured for UDMA/100 [ 76.806715] ata1: EH complete - Note that booting 2.6.27 does not produce any disk error. smartctl - reports no disk health problems, either. + Note that booting 2.6.27 does not produce any disk error. smartctl reports no disk health problems, either. + [update] the bug is present in previouos versions too, and it only appears when using the ahci dirver for libata (see lspci -vv output below). lspci -vv for IDE controllers: 00:1f.1 IDE interface: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE Controller (rev 03) (prog-if 8a [Master SecP PriP]) Subsystem: Sony Corporation Device 81b9 Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin B routed to IRQ 18 Region 0: I/O ports at 01f0 [size=8] Region 1: I/O ports at 03f4 [size=1] Region 2: I/O ports at 0170 [size=8] Region 3: I/O ports at 0374 [size=1] Region 4: I/O ports at 1880 [size=16] Kernel driver in use: ata_piix Kernel modules: ata_piix 00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 03) (prog-if 8f [Master SecP SecO PriP PriO]) Subsystem: Sony Corporation Device 81ba Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin B routed to IRQ 18 Region 0: I/O ports at 18c0 [size=8] Region 1: I/O ports at 18b8 [size=4] Region 2: I/O ports at 18b0 [size=8] Region 3: I/O ports at 1894 [size=4] Region 4: I/O ports at 18a0 [size=16] Region 5: Memory at 80004400 (32-bit, non-prefetchable) [size=1K] Capabilities: <access denied> Kernel driver in use: ata_piix Kernel modules: ahci, ata_piix -- ata timeout exception with ahci libata driver (was with 2.6.28-11, but i confirmed it affewcts previous kernels too) https://bugs.launchpad.net/bugs/352197 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
