I have an older PC with limited acpi capabilities and 2.6.17-1.2141_FC4
Code:
CPU type : AMD Athlon(tm)
Processor CPU speed : 856.102 MHz
Cache size : 512 KB Bogomips : 1714.25
Processor ID : 0
Bus mastering control : no
Power management : no
Throttling control : no
Limit interface : no
Active C-state : C1
C-states (incl. C0) : 2
But it does have:
ACPI: (supports S0 S1 S5) and /sys/power/state == "standby disk".
If I do a echo -n "standby" >state, then it appears to suspend for 1-3
seconds, power light blinking, etc. Then comes back to life. I cannot
figure out what is waking it up. acpitool say all wakeup devices are
disabled.
# acpitool -w
Device Sleep state Status
---------------------------------------
1. PCI0 1 disabled
2. KBC 1 disabled
3. USB0 1 disabled
4. USB1 1 disabled
Here is the system log. The acpi log has nothing in it.
