I played around more with my laptop yesterday and came up with this: The weirdness in X is caused by having drm compiled into my kernel, if I remove drm, S1 works fine again. Even if I suspend/resume in single user and then try to start X in multiuser after resuming X is still hosed. I thought for a while S1 wasn't working because ata1 takes a _long_ time to reset its' devices even though I have no devices on ata1. (I have a removable CD drive that hooks up to ata1 when it is inserted.) I haven't tried with the CD drive hooked up to see if that shortens the reinit time for ata1. S3 is a more complicated story. I have never gotten it to resume ok on my laptop except that during one set of tests yesterday in single user, it did work ok with the kernel with drm compiled in. Today during my tests, I can't get S3 to resume ok in single user mode either with the drm kernel or the drm-less kernel. Both kernels were with yesterday's sources btw. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/
