http://bugzilla.kernel.org/show_bug.cgi?id=13365 Summary: 2.6.28+ cannot read a hard-drive properly through an "82801DB (ICH4) IDE Controller" Product: IO/Storage Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: fun2program8@xxxxxxxxx Regression: Yes Created an attachment (id=21496) --> (http://bugzilla.kernel.org/attachment.cgi?id=21496) lscpi -vvvnn This used to work in 2.6.27. It seems 2.6.28 or greater (tested with 2.6.28-gentoo-r5 and the latest stable on kernel.org, 2.6.29.4) cannot use the Intel 82801DB (ICH4) IDE Controller properly. The kernel will boot fine, and the init script will be launched, but as soon as fsck does a check on whether the partition is /really/ fine before the init services mount it, everything stops. fsck complains that there's a different superblock count (few thousand difference) than what the partition table claims. If I bot back into 2.6.27 after booting into either of these kernels, fsck will complain in a different way that there are errors in the file-system, but it cleans it up and boot continues. If I reboot again into 2.6.27, then fsck doesn't complain at all. However, as soon as I attempt .28 or .29, things go awry again. Attached is lspci -vvvnn output.

Besides the Gentoo kernel and the vanilla kernel, I also have a unionfs patch. However, I have left it out of the mix for 2.6.28 and .29 to make sure that wasn't the cause. This is my first _kernel_ bug report (*shiver* ;), so let me know if I'm missing any info you need. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
