Okay, so why isn't SATA hotplug working in linux-3.3.2 ?
I don't know when it stopped working, but it's a blooming pain in the sysadmin.
I need to hotplug a SATA drive into an AHCI port,
preferably without having to reboot first.
Is there a patch available already for this regression?
Answering my own question, this patch appears to address the issue.
I'll test and report back again shortly:
http://patchwork.ozlabs.org/patch/146326/
Odd that it's been sitting in various people's inboxes since 3.3-rc1
and hasn't been pushed out yet.
The vast majority of "hotpluggable" ports are not necessarily covered by this patch.
And what majority of ports are currently broken by linux-3.3 ?
Any idea of what the offending commit may have been,
so I can test against that and perhaps get it reverted then?
So far, my sample of three systems are all broken with this kernel.
That's definitely "regression" territory. :)
Right -- rather than breaking a bunch and fixing a few, we might just
need to revert the runtime pm stuff altogether.
