Hello Tejun,
since commit 305d2a (unify mechanism to request follow-up SRST) no
devices behind my sata_nv are recognized anymore. Driver reports
correctly link speed 1.5GBps (for CDROM) and 3GBps (for harddisk), but
devices themselves are not found, and so boot fails. Reverting this
commit fixes problem...

libata: unify mechanism to request follow-up SRST
Controller in question is:
00:08.0 IDE interface: nVidia Corporation MCP61 SATA Controller (rev a2)
00:08.1 IDE interface: nVidia Corporation MCP61 SATA Controller (rev a2)
Also another problem - which is too hardware demanding to bisect, but
maybe you will know what's going on. I have Sil3132 with external
enclosure with PMP (sil3726), which is usually powered off. When I
power it on with Windows, all 4 disks are enumerated in ~20 seconds -
just as they spin up one after another, without any resets. Under Linux
up to 2.6.25 it took ~2 minutes, with two complete resets for each of
drives (start spinup on first disk, two complete resets of enclosure,
start spinup on second disk, two complete resets, ...). With current
git (up to commit 3925e6fc1f774048404fdd910b0345b06c699eb4) it even did
not come up at all - enclosure says that all 4 disks are online, but
somehow kernel gave up on PMP and started talking to drive 0 only
(problem is with change above reverted, as without this my system does
not even boot, not even talking about external disks):
