I have a Sony Vaio Z laptop with an internal Intel 3000M card and a discrete Radeon HD6700M card which is connected via the new Intel LightPeak/Thunderbolt port. Intel card works fine, Radeon card fails on drm init with invalid rom contents (attached is the full dmesg with drm.debug=15)
[drm] initializing kernel modesetting (TURKS 0x1002:0x6740 0x104D:0x9084). [drm] register mmio base: 0xC0200000 [drm] register mmio size: 131072 radeon 0000:16:00.0: Invalid ROM contents radeon 0000:16:00.0: Invalid ROM contents [drm:radeon_get_bios] *ERROR* Unable to locate a BIOS ROM radeon 0000:16:00.0: Fatal error during GPU init
The interesting part is that xorg detects a card on PCI:22:0:0 bus and if I specify that as the BusID (xorg.conf) the radeon driver loads and TURKS complains that it requires KMS. If I use PCI:16:0:0 as the BusID radeon does not detect a card at all. According to lspci there is nothing on bus 22:00 but I think the Intel card provides that address as the location of the discrete card.
Any ideas what I can do to get this working?
