Setting
Bus
Speed
at
Boot
If
running
a

kernel,
a
module
parameter
is
provided
to
allow
for
setting
the
maximum
bus
speed
at
boot
time
before
the
iprinit
utility
runs.
Normally
this
should
not
be
needed,
but
if
you
are
having
difficulty
booting
due
to
running
at
160
MB/s,
bus
speed
can
be
lowered
to
80
MB/s
by
using
ipr.max_speed=0
on
the
kernel
command
line.
