Thank you for the clarification.  When I see WARNING: at fs/sysfs/dir.c:455 sysfs_add_one+0xc1/0xf0() I think kernel problem.  If I saw WARNING: BIOS is trying to register things with the same name in the same directory, I would have thought BIOS issue.  Maybe you could make the warning a little more clear the problem is in the BIOS and not the kernel?

I already have an open service request with HP to fix three other bugs in their BIOS.  I will add this to the list.  Now if I could just get someone from HP to contact me and fix the problems.....

Thanks,
Greg
