------- Comment #5 from h...@hmh.eng.br 2009-02-23 17:33 ------- Well, I have a patchset here that seems to fix it. But as far as I can test, nothing turns the resources off later (might be USB braindamage, I don't know if other PCI device drivers do the proper thing and set devices to D3 when unloaded). Anyway, I am worried that we would get dangling pointers when, for example, modular ehci-hcd or uhci-hcd are removed on thinkpads (where they are linked to a power resource), since they do NOT power down the device on removal... so, the power resource still keeps the reference to the now rmmod'ed ehci-hcd device. Right now we don't trigger this because power resources for already-at-D0 devices were just plain not being registered in the first place. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
