VMs not working since 5.2.44

[Hernán Freschi]

Hello,

I'm having some problems with Virtualbox since the upgrade to 5.2.44. My
linux VMs stopped working. I get " failed command: READ DMA EXT" , status
DRDY ERR , error IDNF, etc. As if there was a disk error somewhere.

The backing store is a VMDK pointed to a ZFS zvol.

When I was in FreeBSD 12.1 I could downgrade to 5.2.34 and VMs would start
working again. but on freebsd 12.2 I can no longer downgrade, not even via
ports, so now my linux VMs are no longer accessible and I'm not sure what
could be the problem.
