Specs:
blob free coreboot on a kgpe-d16 (amd opteron)
Happens with both the livecd/usb and a kernel I compiled on another
machine (however with that one I simply get a black screen and a bootloop)
Other distros kernels work fine, it is just gentoo.
The livecd and compiled kernel work fine on all my other computers/VMM's.
Upon loading I get to amd performance counters, it freezes and 5-10 secs
later I receive stack trace for kthreadd "hung" (amd_pmu_init - seems to
be the primary reason) I never get to a login prompt.
It isn't microcode related as I removed the microcode packages from the
other distros I tried.
Any ideas? Is there any additional info that would be helpful? How can I
dump the boot text?
