you have a full crash dump with symbol names? Though if the crash is in
the filesystem code, you'll need to report it to the appropriate
filesystem list.
As for the above ext3 errors, given the message "IO failure" it may be a
hardware problem.
What kernel are you using? What U-Boot?
Do you have all relevant errata worked around, especially USB errata?
There's a USB erratum that basically says high speed mode can't be used
except on specially screened chips.

corruption in your host filesystem. I don't see how that is related to
virtio or KVM -- as far as the host filesystem is concerned, QEMU is
just an ordinary userspace process doing I/O.
Right, this is not supported on ppce500.

Yes. The closest real-hardware analogue would be either a non-legacy

PCI device, or the CCSR SATA device that can be found on some similar
chips such as p3041. The latter is not supported in QEMU, and I don't
know what would be involved in the former.
