Thanks for the serial console logs.
I see that you didn't add rootwait to the command line of your 3.14 boot.

Please do that so that we can see that output.


I'm pasting a diff of them for the benefit of others.
The obvious things to me are:

In 3.13 the device appears after btrfs is loaded:

Same for me though, and I can boot.

[    2.384645] Btrfs loaded

So I don't think the order is it. The biggest difference I'm seeing between the 3.13.11 and 3.14.1 dmesg's provided:

3.13.11:
[    1.861740] bio: create slab <bio-1> at 1
[    1.863389] Btrfs loaded

3.14.1:
[    3.949312] bio: create slab <bio-1> at 1
[    3.950942] Btrfs loaded

It's happening much later, and it's right at this point VFS complains:
[    4.182603] VFS: Cannot open root device "sda2" or unknown-block(8,2): error -38

The 8,2 message is consistent with the kernel not knowing what file system sda2 is. Seems like it's saying "I see sda2, I know you want to use it as root, but I don't know what's there - *poof*" and it panics.

If rootwait alone doesn't work, I wonder if root=uuid=2ba08fbc-4b95-46cc-b638-299f16462620 instead of root=/dev/sda2 will work along with rootwait. It should then wait for that fs uuid to become available, rather than waiting for sda2 to become available.

I vaguely recall there recently being btrfs boot problems with the module compiled in…

Yes, it was with the crc code.  I noticed he has compression on and I'm 
wondering if we're hitting a similar ordering problem with the zlib init.

The best way to know for sure is to please try with an initrd.  If that 
does work we'll know it's an init ordering problem and we can track it 
down from there.

It does indeed wait, but I did not wait for it - just booted, saw it ended
in

"Waiting for root device uuid=..." and pasted the serial output.

Is it supposed to somehow find its rootfs later?

This will have to wait, though. Busy right now.

That's what I'm thinking too...

Everyone:  I didn't think of this earlier, when I first saw the thread, 
but coming home and catching up after work, I think my subconscious must 
have been working on it all day, and even before I read this message, I 
was wondering if it might be another variant of that CRC32 problem.  I 
was impatiently going thru the messages to see if someone mentioned it 
before I started another subthread on it... and here it is. =:^

But both crc32 and crc32c are loaded at about the same point in both 
kernels, before the filesystem tries to load, so that can't be it.

But your zlib theory looks like a good candidate, Chris (Mason), and my 
sysadmin's intuition is behaving like a Geiger counter at Fukishima ATM, 
so I think we're on the right track! =:^)

Indeed, altho as I know from experience, reading/writing that is a lot 
easier than actually setting up an initr*, if you've not used one in a 
decade and haven't the foggiest how to create one.  (Being a gentooer 
here, I ended up following a recommendation from an only semi-related 
gentoo discussion, and setting up dracut for my initr* when I needed one 
to support a multi-device btrfs rootfs.  Wasn't too hard, but I did need 
to set aside some undisturbed time to study up on it and get it 
configured and working.  Since this thread's about a single-device btrfs 
rootfs, he got away without one until now, but...)

Meanwhile, if an initr* bypasses the issue, the fact that I'm running a 
multi-device btrfs root here, and thus an initr*, would explain why I 
hadn't run into the problem, here...  There goes that Geiger counter 
again!
