Public bug reported:

I have a SATA port multiplier, Sil3726 based which works fine in Jaunty
(LiveCD) but breaks under Karmic.

The multiplier seems to be recognised, but then when the drives get
detected they appear to cycle between 1.5GBit and 3GBit link speed
infinitely and the boot never completes. This leads to a useless system
with the port multiplier attached....

In Jaunty boot completes successfully and I can see (and use) the disks
just fine.

I'm not at all sure where the fault is here - it happens pretty early on
in boot so I'm going to assume kernel.

I'm using a 2.6.30 flavour kernel in Karmic and a 2.6.28 one in Jaunty.

One further note, I'm using root over NFS... but this should not make
any difference!
