Many thanks for the link.
Firstly I found that I was resuming immediately - I think this was due to PCI
wakeup - after disabling that in the bios I got suspend working.
I've also got resume working ... well sort of. On resume I get a shell but
lots of I/O errors to my (sata) disk. So it looks like a sata driver issue.
Googling, it looks like I might need 2.6.19 kernel ... not sure if there is a
convenient deb for mythbuntu.
