I haven't tried since 5.5. Have you tried it again with 7|8|9?
I realise that machines supporting S4BIOS are becoming rarities (a bit
like real modems vs 'winmodems' I guess) but has anyone heard of anyone
succeeding - or failing - to hibernate with machines that used to work?
I'm pretty sure I'd have noticed posts/PRs re this, in acpi@ at least.
The 1500c is still in service, still using APM, so I can't pull it down
to test either this or its big issue with ACPI back then (not switching
to battery power on loss of AC - clunk!) Maybe when I get a Soekris or
similar box going, paqi can be put out to pasture for its 12th birthday,
like an old working horse :)
