Uh - I don't have any precise info on this, but I do have the observation that using apmd (*d*) has always had this effect for me since 1.2.13 at least. Don't run it. It intercepts output from /dev/apm_bios that seems to be better left alone. I suspect that what is going on in my case is a syscall numbering incompatibility with various patches that is triggered off just here. See what happens if you don't run apmd. It won't affect the suspend/resume features.
I have the apm_bios 0.5 (patch for 1.2.13) distribution and whatever made it into the 2.0.0 kernel. I have apmd 2.2.
Launching xapm under X (!!) locks the machine after about 30s.
I am running kernel 2.0.0 (and 1.2.13 and 1.99.11). This is an ibm tp500 with phoenix bios.
