Are there ahci problems with > the generic entries, that remain unresolved? It seems JMB363 on MSI Neo2 motherboard (P45 + ICH10R) still doesn't work correctly, flooding the kernel logs. No SATA devices connected, a CD-ROM connected to PATA (and it works fine). I've sent a report to the IDE list some time ago, please let me know if you need more details or testing etc. JMB363 set in BIOS setup to non-RAID mode (it seems this means disabling the JMB BIOS). Last tested with 2.6.32.1 x86-64 SMP. IRQ 16 is shared. Currently the IRQ in PCI registers is 10 (JMB363 SATA is not handled), I can enable and check again if needed. 02:00.0 SATA controller: JMicron Technologies, Inc. 20360/20363 Serial ATA Controller (rev 03) (prog-if 01 [AHCI 1.0]) Subsystem: Micro-Star International Co., Ltd.

Maybe setting the mode to RAID (= enabling the JMB BIOS) would fix it? I can check if there is non-zero possibility. I can't rule out a hw problem, though I think other people had similar problems with this chip. -- Krzysztof Halasa -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
