| |
Hi Patrick & all,
Here's a little patch to make pmdisk suspend to disk work on my old laptop. Basically at least the PMDISK_SIG never got to the disk, and finding the suspend image would fail without this patch. The patch is against linux-2.6.0-test7.
Pls cc me on any replies, I'm not on the list right now.
Regards,
Tony
