Hey, got a question about your blog. I noticed it loads pages lot faster than mine. Do you host your blog on dedicated server? thanks.

Hi Charles,

I’m sorry to hear that – I had the same error with an earlier Intrepid kernel update. It’s more of a temporary annoyance than a serious error, and easy to solve – just wait a few seconds after the error message appears, then at the “(initramfs)” prompt, type:

exit

and press return – booting should continue as normal. If the (initramfs) prompt doesn’t appear, just press the return key a couple of times first.

Once your system has booted, open up a terminal, then edit the menu.lst:

gksu gedit /boot/grub/menu.lst

and add rootdelay=100 to the end of the kernel line, as follows:

kernel /boot/vmlinuz-2.6.27-xx-generic root=UUID=xxxxxxxxxx ro splash rootdelay=100

Save, and reboot – it should boot as normal.

Finally, remember to apply this change to menu.lst with each new kernel update, or the issue will reoccur.

I hope that helps.
