Maybe totally not relevant to what you are having - I am going to try 12 and Xen 4.12.1 soon. I also don't have "iommu=required,force" in my Xen commandline: "dom0_mem=4096M dom0_max_vcpus=1 dom0pvh=1 com1=115200,8n1 guest_loglvl=all loglvl=all vga=text-80x43,keep console=vga" smime.p7s Description: S/MIME Cryptographic Signature

Re: i/o is very slow on FreeBSD dom0 with Xen-4.12 and Freebsd-12
hello Roger. Sorry, my bad. I didn't even look at the cause of the panic. Rebooting the system caused it to come up clean after another pass with fsck. With the ioapic_ack=old argument, the system comes up right away and is quite responsive. Can you explain how to select which argument to use on the command line if the autoselection code doesn't work?

Ie: I'm not sure this is caused by Xen or rather by underlying errors in the filesystem. At least there are no hardware errors on the log AFAICT.
