I run Debian Sarge on my laptop which has APM (1.2) and ACPI (2.0). Almost
everything on my laptop works (haven't tested the modem, but well) - see
However, suspend/resume and hibernate do not work. And since my laptop had
APM capability, I decided to compile a kernel with at least suspend/resume
working. My kernel configuration is at
My network configuration, described in the first link, has eth0 - wired
ethernet (e100 driver) and eth1 - wireless network (orinoco_cs driver).
However, when the kernel booted (passed apm=on acpi=off options), DHCP (as
usual) was attempted before PCMCIA was started (which is eth1). eth1
appeared as Null, while hotplug tried to find an eth2 !
Other symptoms :
1. My battery (which was fully charged and the laptop was running on
battery) was showing 0% charge and charging (from the icon) in KDE.
2. The PCMCIA wireless card had a steady light on (which is the case when
it has detected a network and an essid) but showed no info on the essid in
iwconfig (which returned an error that eth1 did not exist or some such).
