Bug Description
Hi.
This is from http://
Using Debian sid with 1.5.0-5 my Linux VMs (also Debian sid) are broken. When they boot I get gazillions of ATA errors inside the guest, as well as:

in the host.
Please have a look at the Debian bug, for screenshots and more info.
The problem didn't occur in 1.5.0-4 and there were basically no changes inside the VM (i.e. no kernel upgrade or so).
Thanks,
Chris.

For the record, the difference between debian qemu 1.5.0-4 and 1.5.0-5 is the 1.5.1 patch - I applied it without actually changing the "upstream" version number.
