This reverts commit a0710f79. In qemu-devel email message <556DBF87.2020908@de.ibm.com>, Christian Borntraeger writes: Having many guests all with a kernel/ramdisk (via -kernel) and several null block devices will result in hangs. All hanging guests are in partition detection code waiting for an I/O to return so very early maybe even the first I/O. Reverting that commit "fixes" the hangs. Reverting this commit for the 2.4 release. More time is needed to investigate and correct this patch.
