...
still happens in v1.0-2147-g51006bb.
always reproducible with ttylinux 14.0 iso.
Triaging old bug tickets ... can you somehow still reproduce this problem with the latest version of QEMU (currently v2.9), or could we close this ticket nowadays?
[Expired for QEMU because there has been no activity for 60 days.]
