System resumes and is active on the network, so I can SSH into it, but the keyboard and touchpad apparently aren't reinitialised properly and won't respond. Note that the system hasn't hung, but the keyboard and mouse are "frozen". 2.5.44: System suspends, backlight isn't turned off, system resumes and is active on the network. The keyboard is again hung, but if I cycle the input drivers (rmmod then modprobe i8042, atkbd) it responds again. I've actually written a small script which turns the backlight off using DPMS, suspends the system, then cycles the input drivers on resume. I'd much rather use 2.4 though - PCMCIA is utterly broken on this machine in 2.5, wheras it's only a bit broken in 2.4. Is this a known problem? If so, are there any work-arounds? Or if it isn't, is there anything I can do to help debug it? I don't know much about ACPI and the Linux implemntation and I don't have enough time to sit down and understand it so I'm not sure where to start...
