2.6.2-rc1 / libata 0.81 / sata_sil 0.52

[Lars Täuber]

Hallo everybody,

I'm not subscribed to this list! But I read the archive nearly regularly.

But I want to offer a bug-/problem-report.

We have here a dual opteron on a tyan K8S Pro (S2882) with an onbaord SiI3114 and liked to get the system booting from the SATA disks attached to this controller. (SuSE 9.0 x86_64)

The driver works really good if you attach at most 2 disks on certain channels.

After realizing that this kernel (and previous kernels with patches from Jeff Garzik) won't boot with 3 or 4 disks attached we compiled the sata_sil driver as a modules and boot from an scsi disk.

The controller seems to have some connections between the 1st and the 3rd channel as well as between the 2nd and the 4th channel.

If we attach disks on the [1st and (the 2nd xor the 4th)] channel every thins works as expected.
The same behaviour if we connect disks on the [3rd and (the 2nd xor the 4th)] channel.

But if we connect disks on the 1st and the 3rd channel the 'modprobe sata_sil' hangs an we get the following log:
[same when we connect disks on 2nd and 4th channel]

If we can help with further log or testing please contact me at my original mail address.
But I'll read the mailing list to form time to time.


Sorry for my poor english.
