I say NOTABUG because: 1) Writing into the IO space of any device randomly would have 'undefined' results (I'd bet a real machine would fail if you did the same thing) 2) Only a privileged user or device driver can do this 3) QEMU didn't crash or do anything nasty to the host. If you manage to get QEMU to crash or to write to a device/file that it shouldn't be allowed to on the host then that would be a real problem.

Hi dgilbert, Thanks for your comment, and I agreed with it's not a qemu bug, do you think re-open this bug on kernel? No, not a kernel bug either; if you do something random to a disk controller then you can't expect the kernel to like it.

Ok, thank you very much. |
