Hi

I'm sorry to break the threading, but I'm not subscribed and read the list 
irregularly through the list archive, please keep me CCed.

Yes, I can confirm that 2.6.26 guests (on amd64 hosts at least) are pretty 
fragile in virtualbox-ose 1.6.2-dfsg-4 (and earlier 1.6.2 versions) and 
often (but not always) fail to boot very early in the boot sequence. The 
boot failure usually already happens for me before the framebuffer 
initializes, disabling the framebuffer (vga=0) reveals vastly different
panics which are also usually cut (don't fit into 80*25 characters). 

A lot of the cut traces seem to point at HPET, furthermore recompiling the 
kernel with CONFIG_PREEMPT=y enabled pretty much guarantees boot failures
in virtualbox-ose, but Debian's 2.6.26-1-686 2.6.26-2 triggers this issue
randomly (~3 of 10 boots) as well; kernel <= 2.6.25 guests remain to be 
very stable. As a whole it isn't easy to debug or even describe in form of 
a bugreport though, because it just works without changing anything 
sometimes...
