As usual, I have been tracking, building, booting head daily on my
laptop for a while.
Yesterday, having built head at r217090, I had updated to r217145,
built, and booted it OK. (I then booted from my stable/8 slice for the
rest of the day, as usual.)
This morning, I updated to r217189, but on 3 out of 3 attempts to
perform make -j4 buildworld while running head at r217145, the
machine became unresponsive (while the fans were at top speed and
the screen remained lit). I have DDB in the kernel config, but was
unable to break to the debugger.
After the 3 tries, I booted from the r217090 kernel; the make -j4
buildworld was successful.
After booting head at r217189, I re-ran the make -j4 buildworld just
to see if it survived the attempt; it did.
So it *appears* that something after r217090 and before r217146 caused a
problem, and something after r217145 and before r217190 has fixed or
circumvented it. Of course, this isn't an exhaustive test, so take it
with an appropriate grain of salt.
I've attached dmseg.boot for those iinterested.
Peace,
david
