Please use git-bisect(1) to identify the commit that caused the regression. I was unable to hit this code path with qemu-system-i386 with an IDE disk. Please do share your command-line. > assertion "QLIST_EMPTY(&bs->tracked_requests)" failed: file "block.c", > line 1220, function "bdrv_drain_all" bdrv_drain_all() waits until in-flight requests have completed. The assertion verifies that all I/O requests are really done.
