Re: [jornada] Re: Kernel source? (Power managememt for HP Jornada 720)

Just adding my experiences with 2.4.18-rmk3 with John's pm routines
(checked out today, 7-10-2002).

I too see the "hda: lost interrupt" messages and can not get my
microdrive to work due to these.

I also get "eth0: interrupt(s) dropped!" messages but the nic in the
pcmcia slot still functions ok.

As for power management, I can seemingly suspend my jornada.
Here's what the serial console shows when pressing the power button:
-------------------------------------
power [7f]
power [ff]
run_sbin_pm_helper:71 pm_helper_path=/sbin/pm_helper
jornada720_pcmcia_configure_socket(): config socket 0 vcc 50 vpp 0
jornada720_pcmcia_configure_socket(): config socket 0 vcc 0 vpp 0
[sa1100_jornada720.c:216] jornada720_pcmcia_socket_suspend() stub
jornada720_pcmcia_configure_socket(): config socket 1 vcc 33 vpp 0
jornada720_pcmcia_configure_socket(): config socket 1 vcc 0 vpp 0
[sa1100_jornada720.c:216] jornada720_pcmcia_socket_suspend() stub
-------------------------------------

But resume doesn't seem to work :(

Nothing happens when pressing power button again (tried pressing and
holding down for up to 10s) and the recessed reset button has no effect
either. The only way to 'reset' is by removing the battery for a cold
boot.

FYI, I am using a jornada with linux on the flashrom.

Also, to get it to compile, I used the def-configs/jornada720 but had to
remove the #ifdef stuff in arch/arm/mach-sa1100/pm.c around the
#include <asm/arch/h3600_asic.h> line to get definitions for the H3800
compilation complaints.

Tried removing microdrive and ethernet nic, rebooted and had same
results for trying to resume.

So.. I'll head back to 2.4.17-rmk5 (the hda problems are critical for
me).

Also I wonder if tweaking to the bootloader may be necessary. I'm happy
to flash it if an updated version is available.
