I don't see the 'taints kernel' message being responded to here, so apologi=
es=20
if I'm repeating something said in private email.

The kernel FAQ covers this, saying:=20

http://www.tux.org/lkml/#s1-18

 ---- 8< snip snip 8< ----

Some vendors distribute binary modules (i.e. modules without available sour=
ce=20
code under a free software license). As the source is not freely available,=
=20
any bugs uncovered whilst such modules are loaded cannot be investigated by=
=20
the kernel hackers. All problems discovered whilst such a module is loaded=
=20
must be reported to the vendor of that module, not the Linux kernel hackers=
=20
and the linux-kernel mailing list. The tainting scheme is used to identify=
=20
bug reports from kernels with binary modules loaded: such kernels are marke=
d=20
as "tainted" by means of the MODULE_LICENSE tag. If a module is loaded that=
=20
does not specify an approved license, the kernel is marked as tainted. The=
=20
canonical list of approved license strings is in=20
linux/include/linux/module.h.=20

 "oops" reports marked as tainted are of no use to the kernel developers an=
d=20
will be ignored. [...]

So whilst the Myrinet drivers are distributed as source rather than binary =

kernel developers don't have access and so shouldn't be bothered by people=
=20
about any kernel bugs found whilst they are in use.

cheers,
