No.  The first time it looked like yes it fixed it; but when I
rebooted again, same symptoms and same underruns back: this thing is
very erratic.

None at all.

Sometime I should do a bisection between v2.6.36 and v2.6.37 to see
what started the underruns; but I can't promise when "sometime" will
arrive.
