Silicon Image contributed a patch which should help some of the situations that users were seeing. If you are having problems with sata_sil, please do try out this patch.
I'm concerned that the sata_sil blacklist has been growing beyond the older Seagate drives which definitely had buggy firmware; concerned that the Mod15Write fix was simply "fixing" the problem addressed by this patch, simply by hiding the problem behind slow performance. [note: the only way to really know for sure is with ATA bus traces]
Hello, Jeff!
Yes, you are right that the list grew too much.
I, for example, have a sil 3112 controller that made problems (mod15) in the past (crash on big tranfers). But I upgraded the BIOS (and it shows me that even sil firmware was updated) and the problem disappeard.
So, I'll be glad to test this patch, but I can't because now it works very good (I manualy remove the disks from blaklist because they have a match in the list).
Thanks goes to Silicon Image people that, finally, they release a patch to fix this problem.
My motherboard is Intel.
Thanks Jeff.
On platforms where the SiI BIOS isn't executed (non-x86), this patch is probably more critical. On x86, it is purported to only be needed on a single motherboard.
Test results (to linux-ide@vger.kernel.org) would be appreciated, particularly from users with newer Seagate drives.
Finally, there are also a few reports of problems of "screaming interrupts" on configurations with SiI 311x + Seagate NCQ drives. This is a separate problem, and I haven't looked into it yet.
Jeff
