Can you please post the full dmesg of the virtual machine?
Can you also confirm what is the block size you used for the
filesystem on the sd device?
It's pretty odd that the incoming request from the SCSI subsystem
passes a 128k I/O, that shouldn't really happen.
The SCSI subsystem should enforce 64k minphys, but that might be done
only for raw I/O, not block I/O as used for the actual filesystem
operations with a buffer cache.
In general this is purely default NetBSD 10.0_BETA installation. The
only options I changed is adding log, async and noatime to / mount in
the installer.
I assume bsize = 16384 would mean it's 16k? Sorry I can't read dumpfs well.
