In a nutshell, a Mandriva 2008.1 system (Asus A8N5X motherboard) will suspend and resume correctly, but only once. A second suspend results in what looks like a normal suspend - almost. The resulting /var/log/pm-suspend.log gets down to "done running suspend hooks" but shows no evidence it saw any command to resume. Also on the way down the system puts up what looks like the same text on the screen (too fast to read), and then shuts off the display. However, the power indicator stays solid on, the fans are still going, the power consumption is high (measured with a kill-a-watt), and both WOL and the front power button are ignored. Hitting reset is needed to get back into the system.
The hardware can definitely do suspend properly. With XP the system can cycle through standby repeatedly without issues. It drops into the state where the power indicator flashes, the fans are off, and power usage is about 5 watts. Just like in Linux. However Linux can only perform this cycle once successfully. Both the pm-utils in Mandriva 2008.1, and a freshly built/installed version 1.2.3 behaved the same way. I have compared the running processes before and after the one suspend that works, as well as the "lsmod" list. The former list had all the same processes (some shuffling of the order). The latter list differed by two extra modules after resume (sit and tunnel4), but using rmmod to take them out didn't help. Restarting acpid after resume did not help. Further details about steps attempted to diagnose this so far have been posted here: http://groups.google.com/group/alt.os.linux.mandriva/browse_thread/thread/a847ad7a112a488d?hl=en&ie=UTF-8&q=mathog+%22standby+and+hibernate+questions%22#d9fac62c2b66a27b (if that link breaks, google in groups for: mathog "standby and hibernate questions" ) What should I try next?
