Does the kernel expose the DMI tables via the sysfs following sysfs
file: /sys/firmware/dmi/tables/DMI ?
If so, can you do the following:
sudo cat /sys/firmware/dmi/tables/DMI > dmi.raw
and attach it to the bug report. Also a dump of the kernel dmesg log
after it boots may be useful to see if it's a broken firmware DMI table
or a kernel issue.
