Bug description:
The latest version in git (d33ea50a958b2e050d2b28e5f17e3b55e91c6d74) crashes with an assert error when booting a Sparc/Linux guest.

The last time I tried it (about a week ago) it worked fine.  Yesterdai, I did a git pull, make clean, reran configure and compiled.

Host OS: Debian Linux/x86_64 5.0
C Compiler: 4.4.5
Guest OS: Linux/Sparc (2.4)
Command Line: qemu-system-sparc -hda ~njh/qemu/sparc/debian.img -nographic -m 128
Build Configure: ./configure --enable-linux-aio --enable-io-thread --enable-kvm
GIT commit: d33ea50a958b2e050d2b28e5f17e3b55e91c6d74

Output:

Adding Swap: 122532k swap-space (priority -1)

Will now check root file system:fsck 1.40-WIP (14-Nov-2006)

qemu-system-sparc: /home/njh/src/qemu/hw/scsi-disk.c:201: scsi_read_data: Assertion `r->req.aiocb == ((void *)0)' failed.


It crashes in the same place every time.
