I've tested x86-64 from ~1-2wks back, and also had tested around september last year - have been using 32bit as a workaround since it suits my purposes in this situation. > It seem like FreeBSD has a similar problem: > > https://bugzilla.redhat.com/show_bug.cgi?id=881579 > http://forums.freebsd.org/showthread.php?t=36761 I'm not clear from your email - did any of the workarounds work? setting cpu flags, the kvm modprobe option, etc? I was able to boot up when using 'pure emulation' QEMU, (as outlined in original thread IIRC) but this is hardly ideal :D > For now, the only solution seems to be to use i386 on that particual host (or > wait that this is fixed in kvm). > I am wondering why it fails on DF but not for example on Linux.

It does appear that the panic happens consistently for me after 'low level' init and right before mounting the root filesystem - IIRC this is when the actual buffer cache/VM etc is setup, and so presumably lots would be going on w/r/t memory pages/interrupts/etc in a fairly OS-dependent manner. My thought was to add some spurious printfs here and maybe throw in some ASM noops in the right places to see if that allows any narrowing down of the problem, but again, I haven't had a chance to get a proper dev env setup in this environment. Unfortunately my time will likely be short until at least mid summer. GRR! need more unix time! ... and while I'm at it - this + Bug#2133, etc. seem like excellent examples of the 'why keeping >=2 platforms going is a good idea' argument. </soapbox> will forward to bugs@ to get a thread going there.
