My laptop definitely experiences the ACPI+APIC troubles, but I'm not sure whether that is what you refer to as "victim." :) However: suspend/resume _almost_ work under 2.6.x -- the problem is the AGP code, it seems.=20 If I disable AGP, DRM/DRI and the intel framebuffer (which depends on intel AGP! vesa fb is activated and works, though), compile at least yenta_socket as a module, I can do suspend to disk (swsusp2) on kernel 2.6.2 and resume even while X11 is running. The moment I enable AGP (no DRM/DRI, no intel fb), things break. As for S1/S3, it seems that S1 is almost/more or less working, but I can only wake up the machine with the power button and that creates an event to shut down the machine. :-/ Oh yeah: and the keyboard is broken after resume from S1. On S3, the machine comes back up -- apparently with working keyboard, although I can't be 100% sure -- and the screen is dead. After typing "ifup eth0" on the console I can log into it over the network, though. :) On the swsusp2 list, someone made a survey and found out that noone has AGP working on 2.6.x for their Centrino notebooks. So the problem really seems to be with the graphics/AGP/ACPI support of the Intel 855GM/PM chipsets. Is there any way people can help to make sure someone finds the time to look into this?
