So many todos, so little time. Hello again, Thank you all very much for your answers. Actually I use qemu with GDB as described here (-s -S, etc.), I've just posted the simplest command that I use to trigger the bug. So regarding your answers I would like to ask for some more clarification: * Has anyone encountered/reproduce this problem on your ARM host? * Any suggestion where to look in the KVM source for these kind of problems? * Maybe there is some unstable feature that I could disable in host/guest to narrow this issue? Thanks again for all your help! Best regards zbb _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
