Machine shut off after tons of lsi_scsi: error: MSG IN data too long

This bug has been copied automatically from: https://bugs.launchpad.net/qemu/+bug/697510

The problem mostly happens during our backup, syslog does not have any
problematic messages.

Host is Ubuntu 10.10 x86 64 bits
Guest is Windows 2003 Server 32 bits
Using Virtio and Red Hat driver I get a STOP screen 0x100000d1 and machine
either reboot, stay frozen or shut off.
Using SCSI the machine shuts off and I get tons of message on stdout;

I can include minidump file if needed.
I am currently using IDE and it seems OK.
