This is the dmesg output from kernel version 2.6.27.10.
This is the most important part of the dmesg output.

---- STARTS TO BOOT UP NORMALLY HERE ----
So basically, it won't boot if your rootdelay is under roughly 70 seconds.
Can you please post kernel boot log from working (older kernel) setup? I will tomorrow as I am not actually at the computer now. I will also post a log of it totally timing out if the rootdelay is under 70 seconds. Created attachment 19973 [details]

What happens if you disable pata_acpi? (In reply to comment #8) > What happens if you disable pata_acpi? > What boot command is that? It's distro specific, so you'll need to dig documentation of your distro. Tried it - didn't work. Can you please post kernel boot log? Created attachment 20142 [details]
Dmesg output - 2.6.27.10 timeout with noacpi
The rootdelay option was not set, therefore it timed out.

Dmesg output - 2.6.27.11 boot with noacpi
It booted because I had rootdelay set.

Dmesg output- 2.6.28.4 boot with all_generic_ide
This is 2.6.28.4 booting with all_generic_ide. A side effect of all_generic_ide is very high swap and cpu usage.
In all cases, pata_acpi was still being probed before pata_sis. Can you please try to take that out? |

Hard Drive: Seagate ST380023A 80GB (scsi0) IDE Interface: Silicon Integrated Systems [SiS] 5513 [IDE] (prog-if 80 [Master]) --- Subsystem: Sony Corporation Device 8133 Problem Description: The root file system fails to mount on any 2.6.27 kernel using a SATA drive. 2.6.24 is working. To get around this issue, you must use the all_generic_ide or ata_piix boot options in conjunction with rootdelay=120. rootdelay=240 works too if you don't want to use one of the aforementioned boot options. Steps to reproduce: Install a 2.6.27 kernel on a computer with the same hardware as me and reboot.
