I've not been around long enough to know the whole history for sure, but it appears that Nigel has worked for quite some time on swsusp on 2.4 and Pavel has worked on a 2.6(pre) as different branches some original "swsusp". Now that Nigel is going 2.6 the two branches are rather different and hence Nigel's 2.6 version is called swsusp2 while his 2.4 version is just swsusp. Somewhat confusing... So far Nigels stuff is only available as a patch. >>[...] Some of us think this is related to the agpgart rewrite for >>2.6.x, but our patching so far have not made any difference.

No crashes at all, but a handful of failed suspends while hunting down some incompatible drivers - for instance the LinuxAnt driver for the builtin wireless card... / Jonas -- Jonas Petersson | XMS Penvision | mailto:Jonas.Petersson-7RBX4Gk6oWI@public.gmane.org Box 3294, Västgötegatan 13, S-600 03 Norrköping | http://www.xms.se/ Tel: +46 11 400 13 00 | Dir: +46 11 400 13 05 | Fax: +46 11 10 30 50 ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
