Default Bug#583120: Test with 2.6.39-2-686-pae

Hi,

I run basically the same tests as intrigeri did with linux-image
2.6.39-2-686-pae (installed in a squeeze system).


single user mode with KMS
=========================

1) boot in single user mode (see [1] for result of `ps aux`)
2) remove unused modules (see [2] for reslut of `lsmod`)
3) `echo freezer > /sys/power/pm_test` ; `echo disk > /sys/power/state`
the freeze successes (stuff happens then bash comes back)
4) `echo devices > /sys/power/pm_test` ; `echo disk > /sys/power/state`
the screen remains black, power and battery LEDs on, kernel doesn't
answer to sysrq


single user mode without KMS
============================

1) boot in single user mode with `radeon.modeset=0` on kernel command line
(see [3] for result of `ps aux`)
2) remove unused modules (see [4] for reslut of `lsmod`)
3) `echo freezer > /sys/power/pm_test` ; `echo disk > /sys/power/state`
the freeze successes
4) `echo devices > /sys/power/pm_test` ; `echo disk > /sys/power/state`
seems to succeed (stuff happens then bash comes back)


single user mode with KMS, noapic, nolapic
==========================================

Same test with `noapic nolapic` on kernel command line;
Same result as "single user mode with KMS"


single user mode with KMS, acpi=off
===================================

Same test with `acpi=off` on kernel command line;
The system doesn't boot, so I can't test


Hope it helps, feel free to ask for more tests,

K.

Please can you put this information in a bug report on
<https://bugs.freedesktop.org>, under product 'DRI', component
'DRM/Radeon'. Let us know the bug number or URL so we can track it.

I'm always amazed by the number of people who take up solipsism because
they heard someone else explain it. - E*Borg on alt.fan.pratchett
