This is an informational message and would only be worrisome if it reported 0 
bytes left.  You can switch if off by disabling CONFIG_DEBUG_STACK_USAGE in 
the kernel.

Some ebuilds, I have chromium in mind here, can chew up all your RAM and then 
start thrashing swap continuously.  To make matters worse in pre-empting this, 
they only do it for a few versions, then revert to better managed memory 
usage.  On a box with 4G RAM I set MAKEOPTS="-j2 -l2" for such troublesome 
packages and swap usage is kept within normal limits.

I think the message "[drm] HPD interrupt storm" refers to some old kernel bug, 
but it could be a regression.  Which kernel are you using?
