i can reproduce this "[ 0.000000]"-bug with a Thinkpad A31p with a P4M:

cpu family      : 15
model           : 2
model name      : Mobile Intel(R) Pentium(R) 4 - M CPU 2.00GHz

hlt_bug         : no
f00f_bug        : no
coma_bug        : no

for me too - yes

strange, because the cpu supports tsc as the flags indicate in the cpuinfo=
=20
i posted. hopefully this mystery is no more, soon ;-)
