[SOLVED] real time kernel fails to boot

Nareto · 2011-05-17 20:09:58

Hi, I'm trying to install a kernel with the real time patch for audio work.
I've tried both compiling the kernel26rt package from the AUR (which uses the
2.6.33.9_rt31 sources) and the binary provided by the archaudio-testing
repository (which uses the 2.6.33.7_rt29 sources). With both the boot process
hangs; basically it hangs on the message

waiting 10 seconds for device /dev/disk/by-uuid/[root_uuid]

and then gives

root device /dev/disk/by-uuid/[root_uuid] doesn't exist. Attempting to create it.

and then drops me to the recovery shell. Here's a poor quality photo of the
screen with full messages:

The uuid is correct - at least it's the very same as the one for the normal
kernel (which boots fine) as you can see in my /boot/grub/menu.lst posted here:

this happens also with the fallback images.

Any ideas?

The compilation of the AUR package (didn't change anything in menuconfig) and the mkinitcpio for both went fine...
Maybe something having to do with the "keymap" hook?

BTW this is on a laptop

I tried removing the "keymap" hook and adding "ext4" to the MODULES array in mkinitcpio.conf (since my root partition is ext4), but still I get same error.

Also I checked the .config with which the kernel was built and ext4 support, like ext3 (which my boot partition is), is built as a module.

your rt kernel parameter is the same as arch's kernel.it tries to boot arch's kernel with rt initrd. Try changing that

oh, thank you so much it was that easy, I just didn't know you had to change that line also

now the boot process goes past that point but gets stuck on "processing uevents" (with some errors that seem related to the touchpad and card reader) - it seems totally unrelated so I'm marking this as solved

thanks again
