Works for me with -current built today.
This is what the upgrade process looks like over here (hand-copied
from very small font on UEFI console, beware of typos):
root on rd0a swap on rd0b dump on rd0b
iwm0: could not read firmware: iwm-7265-16 (error 2)
iwm0: failed to load init firmware
erase ^?, werase ^W, kill ^U, intr ^C, status ^T
Welcome to the OpenBSD/amd64 6.0 installation program.
(I)nstall, (U)pgrade, (A)utoinstall, (S)hell? u
At any prompt you can <blah blah several lines omitted>
Choose your keyboard layout('?' or 'L' for list) [default]
Available disks are: sd0 sd1 sd2.
Which disk the root disk? ('?' for details): [sd0] sd2
Root filesystem? [sd2a]
Checking root filesystem (fsck -fp /dev/sd2a)...OK.
Mounting root filesystem (mount -o ro /dev/sd2a /mnt)...OK.
iwm0: hw rev 0x210, fw ver 16.242414.0, address 34:13:e8:37:4d:51
iwm0: no link ........ got link
DHCPDISCOVER on iwm0 - interval 3
DHCPOFFER from 217.197.84.34 (fe:e1:54:e3:c3:90)
DHCPREQUEST on iwm0 to 255.255.255.255
DHCPACK from 217.197.84.34 (fe:e1:54:e3:c3:90)
bound to 217.197.84.45 -- renewal in 18000 seconds
Force checking fo clean non-root filesystems? [no]
It has trouble finding firmware at first, which is expected since the
ramdisk does not have it. When the system's root filesystem is mounted,
the firmware is loaded and the device works OK.
What's different in your case?
