No S3/S4 response on Toshiba A70 (FC3)

No S3/S4 response on Toshiba A70 (FC3)

[Gertjan Hofman]

Hi All,

I fear this message is going to sound like one of those 'my mouse doesnt
work, please help' message, but I lack the expertise on ACPI to
solve this one myself.

In brief: I have a fairly new (Nov'04) Toshiba Satellite A70. Phoenix
Bios.  Getting 'sleep' (or hibernate) to work is for me one the most
crucial aspects of owning a lap top. I have had Linux suspend working on
my old Gateway Solo since RH6.2 (when windoze didnt). But this laptop
refuses to do anything.

Bunch more facts: I run FC3, kernel 2.6.10-1.741_FC3smp. I have also
compiled 2.6.10 kernel by hand, but with the same lack of results. Some
ACPI functions are ok - batery power indication, and 'power-button'
produces a normal shutdown -now. CPU throttling seems to work. Thermal
info doesnt.

commands like:  acpitools -s or (-S) dont seem to do anything. Using KDE
tools (Klaptop) does nothing. cat S3 >/proc/acpi/sleep does nothing. No
log file messages or anything.

Lsmod shows
button                 10577  0
battery                13253  0
ac                      8773  0

dmesg | grep ACPI show promising line like:
ACPI: IRQ0 used by override.
ACPI: IRQ2 used by override.
Using ACPI (MADT) for SMP configuration information
ACPI: Subsystem revision 20041105
ACPI: Interpreter enabled
ACPI wakeup devices:
ACPI: (supports S0 S3 S4 S5)

(complete file on web link)


My question is, how do I check why there is no reaction to these sleep
commands. I have included of debug/info files here at the bottom, but they
also available via this link:

dmesg -s40000 is http://koslx1.triumf.ca/gertjan/acpi/dmesg_40000.txt
lspc -vv      is http://koslx1.triumf.ca/gertjan/acpi/lspci.txt
acpidmp       is http://koslx1.triumf.ca/gertjan/acpi/acpidmp.txt
proc/irq      is http://koslx1.triumf.ca/gertjan/acpi/proc_irq.txt
dmesg| grep ACPI http://koslx1.triumf.ca/gertjan/acpi/dmesg_grep_acpi.txt

Any help on how to investigate this further is much appreciated. ACPI
makes all the difference...

Thanks

Gertjan

Pavel,

Thanks for the response and pointing me to the doc file. I quickly tried
the standard FC3 non-smp kernel and now S3 goes into suspend but never
comes back. Not huge surprise. Using a vanilla kernel is a project for the
weekend. Three questions comes to mind - you point me to the swsusp.txt -
is this implying S3 will never work ? Secondly, your video.txt doc makes
it sound like very few video cards can recover from S3. Is this still true
?  Lastly, why is a vanilla kernel better than FC3 kernels ? Feel free to
point me to more documentation.

Thanks

Gertjan

1) S3 is more tricky than swsusp.

2) actually the list is not so short, but tricks are different for
each card.

3) I do not know about fedora kernel. If you want support on
mainstream mailing lists, you should better use vanilla kernels.
