Re: panic on boot
:Something between RC2 and 1.0 seem to be causing triggering
:the following assertion during boot on one of my machines.
:
:assertion:
:gd->gd_vme_base != NULL in vm_map_entry_kreserve
:
:backtrace:
:vm_map_entry_kreserve
:
: -Richard
Richard, please try the below patch and tell me if it works. It looks
like I was improperly decrementing the gd_vme_avail count in the
blockable case (normal reserve) which caused the non-blockable case
(kreserve) to panic.
