>Environment:
HP G71 Notebook  Intel Core Duo 64-bit. BIOS is Insyde and is up-to-date.
>Description:
Created a CD using FreeBSD-10.0-RELEASE-amd64-bootonly ISO.  When booting the BTX loader fails immediately:
	BTX loader 1.00  BTX version is 1.02
	panic: zfree(0xbdb58000,20480): corrupt memlist2


Tried 9.2 version and get same result.  Checked MD5/SHA on my iso images and they are good. 

Is this a known problem?  I searched bugs and email archives and didn't find anything.   Can I help fix it?
>How-To-Repeat:
It happens every time on my Notebook.
