Description of problem:
After closing the lid of my laptop, suspend seems to work fine. System powers down, orange 'suspended' LED light is on.
When pressing the power button to resume the laptop, the system does not resume, but does a cold boots.
I hope it is correct to file this bug against the kernel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. shut lid to suspend
2. press 'power' to resume
resume previous state

After a little poking around, it turns out that this is a generic bug in 2.6.35 as it is also discussed on (at least) the Ubuntu and Arch Linux  forums as well.
The original upstream bugzilla entry for it is here . Comments #82 through #84 on that bugreport mention a patch for 2.6.36 to blacklist systems that need acpi_sleep=nonvs in acpisleep_dmi_table.
As I am not a kernel developer, I have no idea whatsoever what the amount of work to do this would be but: would it be possible to incorporate this patch into 2.6.35 for F14? Not having a working suspend option kinda sucks...
what laptop is this ? Can you attach the output of dmidecode please ?

thanks. I just added a patch for the next build.
I've also posted it upstream, so it should get into future releases.
Thanks! What Fedora release did you patch for? I am still having this problem in the F16 betas, so I'd love to see the patch in there, too.
I added the patch to all branches. Should start showing up everywhere soon.

dmidecode from Sony VPCEB17FX
Same problem occurs with Sony VPCEB17FX.
kernel-126.96.36.199-100.fc14 has been pushed to the Fedora 14 stable repository. If problems still persist, please make note of it in this bug report.
So since this still happens with the Sony VPCEB17FX, should I reopen this bug, or start a new one?
just sent a patch to fix that one upstream. I'll add it to all the fedora trees too. Don't worry about opening another bug. thanks for the debug info.
