Hi Felipe ....

Lucky one ...

I do not even use PCMCIA and don't have the stuff
compiled in or use the modules ... but the reaction
to echo -n '3' >/proc/acpi/sleep is weired.

Somthing like (1) The first time nothing happens
and (2) On the second run the machine reboots....


Up until now I've been slowly upgrading my kernel
from minimal functionality to almost perfect

now USB, and ALSA has been added to the kernel
and I still can suspend/resume....

Now of cause I'm wandering what actually triggers
the crash ....

That might take some time ....

Thanks for the tip

Sebastian

It took some time for me to work, but now ACPI S3 (suspend to RAM) is
finally working for me (I have been trying it since 2.4.22 with no
luck). Only one thing is required before suspending:

# modprobe ds
# cardctl eject

This ejects my CardBus NIC before going to sleep. Not doing so, causes
the system to freeze when resuming.
