I have reported this in March: http://lists.freedesktop.org/archives/dri-devel/2012-March/019731.html Since then, this motherboard received 3 BIOS upgrades (latest is version 1208) and the system was upgraded to Fedora 17. With kernel 3.5-rc4+ (commit 47b514cd476db2eca066a2ad31501b079d6c9cce) plus this series of patches, the reported problem doesn't appear anymore. lspci reports PCIe gen2 speed for my Radeon HD6570 and gen1 speed for my 3ware 9650SE: [zozo at localhost ~]$ sudo lspci -vvv -s 01:00.0 01:00.0 VGA compatible controller: ATI Technologies Inc NI Turks [AMD Radeon HD 6500] (prog-if 00 [VGA controller]) Subsystem: PC Partner Limited Device e193 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 88 Region 0: Memory at c0000000 (64-bit, prefetchable) [size=256M] Region 2: Memory at fea20000 (64-bit, non-prefetchable) [size=128K] Region 4: I/O ports at e000 [size=256] Expansion ROM at fea00000 [disabled] [size=128K] Capabilities: [50] Power Management version 3 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [58] Express (v2) Legacy Endpoint, MSI 00 DevCap: MaxPayload 256 bytes, PhantFunc 0, Latency L0s <4us, L1 unlimited ExtTag+ AttnBtn- AttnInd- PwrInd- RBE+ FLReset- DevCtl: Report errors: Correctable- Non-Fatal- Fatal- Unsupported- RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop+ MaxPayload 128 bytes, MaxReadReq 512 bytes DevSta: CorrErr+ UncorrErr- FatalErr- UnsuppReq+ AuxPwr- TransPend- LnkCap: Port #0, Speed 5GT/s, Width x16, ASPM L0s L1, Latency L0 <64ns, L1 <1us ClockPM- Surprise- LLActRep- BwNot- LnkCtl: ASPM Disabled;
