With this kernel version (comparing to 2.6.23-rc8-mm1) the port probing time goes up from ~0.5 seconds per port/drive to ~2 seconds. Also the SControl changed: 2.6.23-rc8-mm1: [ 4.110000] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) 2.6.23-mm1: [ 5.930000] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 0) But except for increased delay during boot no errors can seen, the drives work normally. > Clarence, it seems it could be that what's broken is irq routing not > sata_sil24 itself I dunno anything about irq routing on PPC440SPE but I > bet there are kernel parameters to adjust them including irqpoll. Do > those have any effect? (Both kernel assign the same irq (17) to the controller. So at least this delay is not caused by irq routing) Part of what I suspect in this case is the ACPI of my bios. As there is one checksum error and the cable detection of the pata port is completly broken, it might be that this delay is also its fault. But as I think that ACPI is limited to x86, I doubt this is related...
