By checking the old 2.4.20 driver used for this device, I've found the following lines : #ifdef CONFIG_BUFFALO_PLATFORM writel(0x10401554, mmio_base + 0x14c); writel(0x10401554, mmio_base + 0x1cc); #endif in the sil_init_one function (in sata_sil.c)... After some google searching, I've found this message from this mailing list : http://www.spinics.net/lists/linux-ide/msg00047.html => It says that for SiI 3114 contoler, we need to force write 0x10401554 instead of 0x10401555 in sfis_cfg (SATA FIS reception config register). By looking in the source code of the latest version, it looks like my controler (Sil 3512) is set to apply this workaround too, but according to my boot log, it's not applying it (It should write "Applying R_ERR on DMA / activate FIS errata fix" just after the error about the PCI cache). I'll add some traces to understand what's happening and I'll tell you ...

This hardware includes a powerpc 603e (running @ 266MHz) and two SATA SIL3512 controllers (as the device runs 4 drives) ... At startup it's getting some problems with the controler, but i'm not able to understand what can be wrong ... I tried with a 2.6.18.2 kernel and a 2.6.19-rc5 kernel, and I have the same problem with both versions ... Here is the "interesting" part of the kernel log (2.6.19-rc5 log): Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx sata_sil 0000:00:0c.0: cache line size not set.

Driver may not function", I was able to force PCI cache function but it doesn't change anything ... I've also tried to compile the kernel with a gcc v4.1.2 with no change ! I really hope someone could help ...
