*** resent with proper date/time. apologies for taking you back to '88 *** Hi all, I'm having quite a challenge getting my Acer TM6460 to resume from suspend with kernel 2.6.22.1-27 (and-33) and using the vesa driver for X. It worked fine with up-to-date FC6: - suspend works with # pm-suspend --quirk-s3-mode - resume fails. The screen remains black (no backlit) and the HD led comes on the first time but from a similar problem with an Acer Ferrari 4005 I know it must flicker afterward which it does not. So I went to the pages at: http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-index.html and followed the advice. The debug info is: [root@localhost ~]# cat dmesg.txt | grep "hash matches" hash matches drivers/base/power/resume.c:28 hash matches device 0000:09:04.1 This device is the cardbus bridge: [root@localhost ~]# cat dmesg.txt | grep "0000:09:04.1" PCI: Bus 10, cardbus bridge: 0000:09:04.1 PCI: Enabling device 0000:09:04.1 (0080 -> 0083) ACPI: PCI Interrupt 0000:09:04.1[A] -> GSI 20 (level, low) -> IRQ 20 PCI: Setting latency timer of device 0000:09:04.1 to 64 Yenta: CardBus bridge found at 0000:09:04.1 [1025:010d] hash matches device 0000:09:04.1 I have no idea if this indicates a problem with the cardbus or not. Afaict the module list below shows no related module.

This did not result in a working resume on the TM6460 either. Anyone have a suggestion what else I can try to get resume going? Thanks! Patrick
