It's an amd64 machine where current/amd64 has always worked.
The dmesg are at http://stare.cz/dmesg/intel-i7.*

Yesterday, I "upgraded" the machine to current/i386.
That's where I observed that bsd.rd boots but bsd does not.
It was an i386 bsd.rd that booted and an i386 bsd that did not.

After ealizing this, I upgraded again, this time to current/amd64
- which works fine, like it always has.

I believe you are right about the inteldrm. Usually, the boot sequence
switches to a smaller font once it gets to graphics. After the i386 upgrade,
it stayed 80x25 before it went black. That's hardly a bug report of course.

Thank you
