Anyone got suspend working on a T43?

Been playing around with a new T43 this weekend, but can't get round a hang when resuming from suspend. Would like to know if it's working for anyone else...?

Have tried FC3, FC4test2, and Ubuntu 5.04 - all show the same behaviour - appearing to hang on the first disk activity after resuming. Have tried APM as well as ACPI (S3) - but seeing the same behaviour.

Thanks in advance,
Jon E.

In /boot/grub/menu.lst look for the line beginning #kopt. Check which drive and partition follows the "resume=" statement, and make sure it is pointing to your swap partition (fdisk -l will list all the partitions on the machine).

It works on my T42. Now. Finally.

Hi Ed, thanks for the suggestion - but this is suspend to RAM. Suspect it's something to do with seeing the drive as an SATA device...

I'm sure you did the steps listed in this link, but just in case, here it is...

This works on a T42; perhaps not on a T43?

Update: Have just been advised on the linux-kernel mailing list that SATA suspend/resume is broken at the moment.
Have some patches for a 2.6.12rc kernel, so will try to build that and test...

It is not suspend-to-RAM, it is suspend to disk, as that line means that when GRUB boots the machine it looks at that path to find a saved session. But it is true that SATA doesnt work very well with the latest kernels (I though T43s still had PATA drives though).

Hmm yes, on re-reading that it appears somewhat ambiguous! I was meaning that my problem was with suspend to RAM, rather than Ed's response....
It's true that the T43 has a PATA drive, but it's presented as a SATA device by the chipset.

Regards,
Jon.

I fixed this wake-up problem on my T43 by patching the 2.6.12 kernel with the sata_pm patch:

Good luck!
