Using
the
Unitedlinux
hwinfo
and
hwscan
utilities
Description:
The
hwinfo
and
hwscan
utilities
provided
in
Unitedlinux
distributions
are
used
to
detect
the
system
configuration
and
to
maintain
the
SuSE
hardware
configuration
database.
Excessive
use
of
these
utilities
can
cause
software
failures
(such
as
process
hangs
or
system
crashes)
that
might
result
in
data
damage.
Typically,
these
utilities
run
once
during
startup
to
perform
a
hardware
scan
and
reconfiguration,
or
to
configure
hot-added
hardware
that
requires
configuration,
or
to
create
a
detailed
report
of
the
system
hardware
and
kernel
configuration
information.
Two
specific
problems
are
known
to
occur
when
these
utilities
are
run
excessively.
These
problems
are
generic
kernel
bugs,
and
they
are
not
specific
to
SLES8
or
the
Unitedlinux
kernel.
Both
problems
can
occur
with
SLES8
or
Red
Hat
Advanced
Server
2.1
for
IPF.
v
IDE
driver
bug:
This
problem
occurs
when
specific
control
commands
are
issued
to
an
IDE
device
while
the
system
is
under
relatively
heavy
load.
A
fix
has
been
identified
for
this
problem,
and
a
patch
will
be
available
when
Unitedlinux
1.0
Service
Pack
1
for
IPF
is
released.
v
Excessive
loading
and
unloading
of
kernel
modules:
Running
the
hwscan
utility
with
specific
options,
such
as
printer
and
storage--ctrl,
causes
process
hangs
and
kernel
panics
because
of
the
excessive
loading
and
unloading
of
the
device
drivers.
If
you
believe
that
you
are
experiencing
such
a
problem,
examine
the
kernel
log
buffer
to
determine
whether
the
kernel
has
a
fault.
A
typical
backtrace
might
look
similar
to
the
following
example:
ia64_pag0x70
statm_pg0x3a0
proc_pi0x410
proc_in0xe0
s0x1c0
Solution:
While
the
server
is
being
used
for
normal
operation,
avoid
running
the
hwinfo
and
hwscan
utilities
excessively,
for
example,
continuously
in
a
script.
In
addition,
avoid
running
any
sequence
of
commands
that
would
result
in
device
drivers
being
loaded
and
unloaded
multiple
times
while
concurrently
running
any
utility
(such
as
top,
ps,
and
so
on)
that
might
access
specific
process-table
attributes.
