When I try to "standby" (echo standby > /sys/power/state) a 2.6.14 system running on a VIA C3-based system with VIA chipset (suspend to disk never worked on this system -- as stated on swsusp website it's due to the lack of some CPU instruction on this CPU [but winXP suspends to disk on this system just fine]), it immediately comes back, with the above error message:
Stopping tasks: =====================================================================| ACPI: PCI interrupt for device 0000:00:07.5 disabled Could not suspend device 0000:00:07.3: error -22 ACPI: PCI Interrupt 0000:00:07.5[C] -> Link [LNKC] -> GSI 12 (level, low) -> IRQ 12 ACPI: PCI Interrupt 0000:00:0a.0[A] -> Link [LNKC] -> GSI 12 (level, low) -> IRQ 12 eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 Some devices failed to suspend Restarting tasks... done
Here's the PCI devices:

(note it's the second USB interface which fails). And here's the USB device list:
Bus 002 Device 002: ID 07cc:0301 Carry Computer Eng., Co., Ltd 6-in-1 Card Reader Bus 002 Device 001: ID 0000:0000 Bus 001 Device 003: ID 0458:0036 KYE Systems Corp. (Mouse Systems) Bus 001 Device 001: ID 0000:0000
This machine was never able to go to standby mode completely - before 2.6.14, it performed resume after several secounds of sleeping. Now it does not even try to sleep anymore.
Also, "suspend to mem" does just nothing, -- the same as "suspend to disk" (but for disk, it never worked at all as stated above).
Any hints on where to look at?
Thanks.
