Bug Description
Binary package hint: linux-image-
package: linux-image-
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:/
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:
[ 75.816137] res 40/00:00:
[ 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.
[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).

Hi Gorgonzola,
Can you comment if any of the previous 2.6.28 Jaunty kernels exhibited this behavior? Care to give the upstream kernel a quick test as well. The Ubuntu kernel team has started packaging the upstream kernels - https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Thanks.
