freebsd stable - May 2009 - loader not working with GPT and LOADER_ZFS_SUPPORT

Hi,

I tried booting from a disk with GPT scheme, with a /boot/loader build
with LOADER_ZFS_SUPPORT="yes" in make.conf. I get the following error:

panic: free: guard1 fail @ 0x2fd4a6ac from
/usr/src/sys/boot/i386/libi386/biosdisk.c:1053

Its a FreeBSD 7-STABLE after the ZFS import.

Booting with /boot/loader copied from a 8-CURRENT system works.

greetings,
Philipp

Same problem for me. I also tried with MBR scheme, same problem.

I had a similar problem (different @ 0x.... address) with -STABLE over
the weekend.  I just wanted to boot an old fashioned system, MBR and
no ZFS.  I ended up building a loader with

  LOADER_ZFS_SUPPORT="NO"
  LOADER_NO_GPT_SUPPORT="YES"

and it worked.

Updated kernel + world yesterday, setting LOADER_ZFS_SUPPORT="yes" in
make.conf

Same symptom, had to revert to the old loader for that.

Prior to that I needed to do a cd /usr/src/usr.sbin/btxld && make  
install clean in order to work around the

btxld: zfsboot.ldr: Invalid argument

problem during building world+kernel
