Problems booting with new kernel

[austinramsay]

I just upgraded to kernel 3.11.6 from 3.10.7-r1. Once i reboot the kernel was loading fine but then it started throwing a couple errors but i couldnt really read them because it just went through so fast. It brought me to the login but it wasn't right, the hostname was unknown, the domain was unknown, and when i logged in it was acting kind of strange like just displaying the $ sign with no name or anything then id hit enter and then my username would finally pop up with the $. Also i found my /boot was not mounted and my root filesystem was read only until i remounted it manually. Is there anyway i can get those errors from a log file so i can post them on here? Or does anyone have an idea on whats wrong?

If the errors were printed by the kernel, they will also be in dmesg. If they were printed by the init system, you may be able to record them using the OpenRC boot logging.

Reason could be -as you wrote- that your root is mounted readonly,

like that /etc/mtab cannot be altered and /boot will not get booted.

However that would not give you the chance to wite any bootlog to a file.

What FS are you using for your rootfs?

If you add "rw" to your grub kernel command line your system should boot normally.

And please grab a live cd and run fsck on your partitions

That makes sense but why would it be setting it as read only? What would cause that? I can boot fine with the old kernel still its just the 3.11.6 thats giving me problems. Im using ext4 for my /boot partition and my root fs. How would i add rw into grub?

[Hu]

The rootfs is usually mounted read-only, then switched to read-write later. Please post your bootloader configuration file.

Fixed by adding rootfstype=ext4 to my grub conf.
