Hard Drives not detected after kernel upgrade.

jivings · 2011-07-15 12:36:15

After the latest kernel upgrade when I boot my system I get the following message:

ERROR: Unable to determine major/minor number of root device '/dev/sdb1'.

I am then booted into ramfs where I can see that none of my drives have been detected.
I have tried downgrading the kernel but the error message remains.

Can anyone shed any light on this? I'm stumped....

I'm with a similar problem after yesterday's "yaourt -Syu", in my case the boot process stops with a message like this:
"Could not stat the resume device file /dev/sda2" and a few other lines.
The previous line mentions libgcrypt version, by the way, don't know if related.
If I select Fallback Mode it boots fine.
Any suggestions welcome!

There has been numerous posts about this before. Have you tried the suggestions from those? http://www.google.com/search?q=site%3Aa … +device%22

Lars, you mean removing the "autodetect" from mkinitcpio.conf?
How safe/convenient is that????

Removing autodetect had no effect for me. I also added the modules mentioned in the same post. No luck...

As far as I know, removing autodetect is poor advice, because that would make it the same as the fallback image, but there are at least a couple of other suggestions in this thread for example: https://bbs.archlinux.org/viewtopic.php?id=103362

If those doesn't help, I've got nothing else I'm afraid.

I got the same problem here fallback works fine, but when I boot
the usual image I get the same error as the OP did.

I even reinstall Arch, and it still displays the same error, so I'm guessing
it's a bug?

I've had this issue with the last two kernel 3.0 updates. The solution (after lots of googling) for me, was to chroot into my install via the instructions on the wiki. Then run the command:

mkinitcpio -v -p linux

Reboot and hopefully it works for you too (and hopefully the bug gets resolved soon as well).

That didn't work for me, what's weird is it's only on the main image,
the fallback is okay.
