Have anyone experienced problems with suspending USB devices on
# echo standby >/sys/power/state ?
The kernel says:
Stopping tasks: =============================================================|
ACPI: PCI interrupt for device 0000:00:11.5 disabled
ACPI: PCI interrupt for device 0000:00:11.4 disabled
Could not suspend device 0000:00:11.4: error -22
ACPI: PCI Interrupt 0000:00:11.5[C] -> GSI 11 (level, low) -> IRQ 11
Some devices failed to suspend
Restarting tasks... done
The device driver is uhci_hcd
# lspci | grep USB
00:11.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1
Controller (rev 1b)
00:11.3 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1
Controller (rev 1b)
00:11.4 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1
Controller (rev 1b)
This happens with kernel from www.kernel.org
# uname -r
2.6.14.3
The original kernel from fedora 4 pack seems to be free of this, however I can
not get why. Compiling my kernel sources with the FC4 config
(config-2.6.11-1.1369_FC4) does not help - USB suspend still does not work.
It seems that FC4 comes with somehow patched kernel.
Any comments?
