This sucks. On some very rare occasions, when I connect an SD card reader to my Ubuntu machine, it freezes. Normally I just reboot and everything is fine. But this time my Ubuntu machine won’t boot, and it shows a message like
Starting up …
Loading, please wait…
kinit: name_to_dev_t(/dev/disk/by-uuid/bd656dcd-04b4-412f-a880-62a6553bd8b) = sda5(8,5)
kinit: trying to resume from /dev/disk/by-uuid/bd656dcd-04b4-412f-a880-62a6553bd8b
kinit: No resume image, doing normal boot…
Then it hangs forever. Any Ubuntu/Linux gurus have suggestions on how to repair my system so it will boot?
Update: I think the machine is fixed now. Thanks to Sérgio Carvalho and Chris Fleming for the suggestions. It looks like somehow my swap partition got messed up, which affected things when my Linux machine got confused about whether my machine had hibernated. The fix was:
– When the machine boots up, press ‘Esc’ to get to the Grub menu
– Select one of the “recovery mode” options. This will boot you up to a single-user root prompt.
– Run “sudo fdisk /dev/sda” (this assumes that your hard drive is at sda)
– Type “p” to see which hard drive partition is labeled “Linux swap”. In my case the partition was /dev/sda5. Type “q” to exist fdisk.
– Type these commands:
sudo swapoff /dev/sda5
(Use whatever partition was labeled as “Linux swap” in fdisk. For me, this was /dev/sda5)
sudo mkswap /dev/sda5
sudo update-initramfs -u
These commands say “Stop using /dev/sda5 as a swap partition,” then mkswap tells your computer to set up /dev/sda5 as a new/fresh swap partition. Finally, update-initramfs with the -u (update) option will generate an initramfs image. The initramfs image is a gzipped blob of data that the Linux kernel unzips into RAM and then mounts to use as an initial file system.
– Type “reboot” and cross your fingers for your machine to boot up. For me, it rebooted just fine and started working normally.
Thanks to everyone who chimed in with an opinion on this.
