After this patch, attempting to boot a kernel results in an abort() a short way into the boot: /home/dwg/ibm/kvm/qemu/tcg/tcg.c:1646: tcg fatal error Aborted I'm not very familiar with TCG - can anyone give me some pointers on how to get the information necessary to debug this? -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
