Hibernate and Suspend
Hi all. Things with Suse 12.2 were fine as far as suspend and shutdown were concerned on both my desktop and notebook computers. The arrival of 12.3 heralded a less than satisfactory behaviour. I have put up with this for some time, but enough! is enough! I have done some reading and discover that suspend writes everything to Ram and then keeps the ram powered up to retain it all, a meagre power demand. Hibernate writes everything open to the swap partition and then on reboot should resume very quickly. Hibernate works for me for 5 minutes but not 8 hours, suspend is also flaky in that the recovery tends to hang with no display. Shutdown hangs on exit unless the previous command was suspend in which case it works as expected. Is this a case of ACPI not being consistent with the BIOS? Should I add "no_acpi" to the grub file? A new release of Suse is only 18 days away, should I see what the upgrade brings? I would be grateful for advice in this, Many thanks Andrew Greig

Personally I'd recommend filing a bug about it and see what the SuSE folks say, the fact that it used to work and now doesn't is strongly indicative of a kernel regression. If there's a new release coming could you try that out with a live USB or DVD image to see if suspend is better? cheers, Chris -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC This email may come with a PGP signature as a file.

Thanks Chris, A new version of OpenSuse is only 9 days away now, so I will follow your advice and if OK upgrade. Years ago Mandrake Linux 8.2 had oustanding support for USB networking, then lost it for the next few releases. Andrew
