Hi,

I can't bring up my machine with root LVM anymore using x86_64. The same 
machine from same kernel tree boots fine as x86. The error message is quoted 
in subject. The tree is at 86a71dbd3e81e8870d0f0e56b87875f57e58222b (for 
those not using git: somewhere after 2.6.20).

Attached are my .config of x86 and x86_64 as well as dmesg of failed boot as 
captured via serial line.

The only other report of this problem dates back to early 2005 (see 
http://lkml.org/lkml/2005/2/5/29) and was about 2.6.11-rc2-mm2. I 
successfully have 2.6.18-rc7-something on this machine as x86_64 so it worked 
in between.

Any ideas?

Greetings,

Eike
