But if this is a regression, I can look at it. Problem is, I don't have the option ROM and I don't think I can obtain one legally. Please provide at least a trace of the SCSI commands that are sent. > BTW: Nearly all KVM coredumps aren't valid anymore and have only a > garbage stack trace. Any ideas? It seems strange that this would be limited to KVM. What about other programs? Or try --disable-pie. Paolo
