There is no support in Linux either for hotplug on the VIA (just =20 checked) and I just ran through the (sparse) docs again to no avail. When I added hotplug for those controllers that support it, I spent =20 quite some time playing with the VIA chips to get them to interrupt =20 when there is a PHY "surprise", but alas I didn't succed. Now the =20 SATA regs shows that there was a change etc, but with the interrupt =20 thats worth close to nothing... S=F8ren Schmidt sos@FreeBSD.org
