loader can't load kernel on FreeBSD 6.1-p6.

[Nikolay Pavlov]

Hi, folks.
While booting 6.1-RELEASE-p6 i have this error on /boot/loader stage:

can't load kernel

ls shows nothing...

lsdev shows me:
disk devices:
	disk0: BIOS drive C:
	   disk0s1: FFS bad disklabel


But when i am booting from LiveCD i see all my labels, i can mount them,
i can produce read/write operations.
Other thing that confused me is that when i am using second stage  
bootstrap file i see my root partition:

FreeBSD/i386 BOOT
Default: 0:ad(0,a)/boot/loader
boot: ?. .. .snap bin boot dev etc lib libexec mnt proc and so on...

But when i am trying to boot kernel (GENERIC) directly from bootstrap 
i have "BTX halted" error, don't know if this actually supported.
World was builded on other box and installed to this drive
using tar.

Here is additional information that i can get from LiveCD:
