Hello Ben,

(CCing Jens here)

I was facing same issue too. Surprising I did not hit the same on the
guest VM.

After bisecting, found that Reverting
[9f4107b07b17b5ee68af680150f91227bea2df6f] block: store 
bdev->bd_disk->fops->submit_bio state in bdev

Helped me to boot back the system. Can you please confirm

Thanks
