Based on the photo on Newegg, it appears your ASUS motherboard uses an ASMedia ASM1083 PCIe-PCI bridge. Given the following LKML thread, it seems that you are lucky it works at all. https://lkml.org/lkml/2012/1/30/216 Anyway, the DH77KC uses an ITE IT8892E PCIe-PCI bridge. This chip seems to be used on some Gigabyte boards, as well as the older Intel DH67BL. The only bug discussion I can find regarding the IT8892E is this old thread on the CentOS mailing list. http://lists.centos.org/pipermail/centos/2011-January/104571.html The relative absence of bug discussions on the net leads me to think that perhaps it is just a problem in the bios on the DH77KC. Do you think it is realistic to think that we can convince someone to fix the bios? I would hate to spend significant time tracking this down, only to have the bios developers ignore us. Please let me know whether you think this is worth pursuing. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
