Yes. Unfortunately the ld drivers differ very much in
what context the start and iodone routines are called.

Should we apply it?

It would only help virtio. Either all drivers must

I thought the panic happens only on the virtio disk driver.
Feel free to apply the patch if we choose the former.

 We have some virtio related PRs:
