Re #8,
By "FAILS", I mean that nothing happens. eg
echo on >/proc/acpi/ibm/light
just doesn't turn the light on. The command takes slightly longer than usual to
complete (about 2 sec, rather than nearly instant), then the prompt returns with
no error message. [I didn't check whether there was an exit code].
I'm not sure that the T22 had the same problem - although I think it is the same
symptom. On an A22p, I don't experience this bug, even with speedstep_smi
Yes I'm sure it was booted with ec_intr=0. I'm repeating the experiment now.
1)Linux2.6.17.1 single
2)cat /proc/cmdline
BOOT_IMAGE=Linux2.6.17.1 root=301 inotify splash=verbose panic=60 ec_intr=0
single
3)init 3
#Services: acpi,acpid on, cpufreq not started
cd /proc/acpi
cat battery/BAT0/state #works
echo on > ibm/light #works. Exit code 0
echo off > ibm/light #works. Exit code 0
modprobe speedstep-smi
cat battery/BAT0/state #works. Exit code 0
echo on > ibm/light #FAILS. Light doesn't come on. Command takes
#2 secs to return. Exit code 0.
dmesg > dmesg.txt
lsmod > lsmod.txt
lspci -vv > lspcivv.txt
cat /var/log/kernel/errors > vlke.txt
Will attach these in a moment.
I hope that's what you need. Any other things I can help with.
