Summary: Bluetooth sometimes does not work after resuming from suspend

Steps:
1. fwts s3 --s3-multiple=30 --s3-max-delay=5 --s3-min-delay=5
2. hcitool scan

Expected results: Can scan and connect to BT devices

Actual results: Can't scan and connect to BT devices

I've installed the kernel mentioned before. It's weird that the bluetooth device is disappear in lsusb. Even when I reboot, then enter the old kernel 3.5.0-22, the problem still existed. I'll try to shutdown and calm down the machine then try it again. Because the battery is hard to remove.

[Gavin Guo (mimi0213kimo)]

I've tried to test again and it seems there are some problem with read error.

Gavin, the patch does not touch any USB thing, and suggest you
to apply the patch against your working kernel to see if it can fix
the firmware loading bug?

Thanks

@Ming,

I've used 3.5.0-22-generic and added your patch with the command "fwts s3 --s3-multiple=10 --s3-max-delay=5 --s3-min-delay=5" tried 3 times. It seems the bug is fixed with your patch.

[Anthony Wong (anthonywong)]

@MIng
Can you SRU your patch as far as to Quantal's 3.5 kernel?

[Adam Lee (adam8157)]

quantal is EOL, closed as won't fix
