This is so widespread and well known that the only person in the universe who bitches about it is.... Michael from Phoronix. For everybody else, its "meh."
What about PCIe hotplug support? I've tested hotplugging on a few Intel desktop and server motherboards with an ExpressCard adapter board. Strangely I could get hotplug going on a Core2Duo board (with PCIEHP force option) but not on a Corei7 board.The change in the Linux 2.6.38 kernel disabled ASPM unless the BIOS advertised support for it, but it turns out a vast number of systems supporting ASPM do not actually advertise it from the BIOS
The only way I could get ExpressCard hotplug working reliably was using ACPI hotplugging on laptop ExpressCard slots...
as for your previous comment, if a stability regression is fixed and causes a power regression then yes they went about it the right way, of course its not nice your laptop used more power but if it was your laptop that would become unstable you would be ranting even more.
it seems to be fixed, be happy and if you can do it better and faster I am pretty sure there is a job for you waiting with the kernel developers.
I'd venture to say ASPM works fine on Windows as the BIOS in most cases is coded to hand off _OSC control to Windows only and not to any other OS including Linux. That patch is a good solution and to enable ASPM for DEVICES that support it rather than for the BIOS then that's a usable solution IMHO.
Nice work Michael!
Yes thats the solution just make it against the LAW no more talk about problems at all.
this is the new age of bug-free Linux solutions. there is no bug because all bugs are against the LAW!
