*** 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.

The results of booting with various parameters are:

Boot param	     result
----------------------------------------------------------------------
vga=792		      no working resume
vga=normal	      no working resume
maxcpus=1	      no working resume
noapic		      no working resume
nolapic		      no working resume
noapic nolapic	      no working resume
nolapic_timer	      no working resume
nohz=off	      no working resume
ec_burst=1	      no working resume
nolapic ec_burst=1    no working resume
acpi=noirq ec_burst=1 no working resume

>From the Acer Ferrari days I remember booting with parameters like
(iirc) noapic acpi_irq_balance irqfixup pci=noacpi. 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
