Can you load your kernel and mod= ules with the loader from the ISO/memstick?

For example, the exact make of mainboard (kenv ou= tput) and the BIOS version, and any relevant BIOS settings are likely imp= ortant for problems regarding the loader. If the kernel and modules load,= you can try a verbose boot to see better how far the kernel gets. >=20 > I=E2=80=99d be really surprised if the CPUs themselves would cause trou= ble. The first step is done. The affected hardware doesn't boot from official 12.0-RELEASE CD either. Loader also freezes at the stage of loading kernel modules. These servers are old Maxdata Platinum 500 and 3200. Some time ago I have submitted dmesgs to NYC BUG dmesg repository[1][2]. Both configurations are fine with 11-STABLE, so I am not going to upgrade them and I am replying only FYI.
