I have figured out that 2.4.18-14 wont mysteriously poweroff my machine if I keep my laptop lid open. 2.4.18-12.5 will keep my laptop on as expected with the lid open or closed. interesting could you try adding apm=idle_threshold=100 to the kernel commandline? that would be the only place where the kernel calls APM code in normal use I am happy to report that apm=idle_threshold=100 appears to work. I am curious, why was it changed? ok can you get me the dmidecode for that machine? It was changed because it saves a LOT of power on the machines that do support this feature properly....

dmidecode with latest BIOS (R0121K5)
https://bugzilla.redhat.com/bugzilla/showattachment.cgi?attach_id=51326 This is the dmidecode from late last year, with an older version of the BIOS. 2.4.18-17.8.0 no longer powers off mysteriously, but appears to lock up instead. I still need to test whether this is caused by the new BIOS or the new kernel, so please don't change anything yet. Okay I have confirmed that this latest version of the BIOS has changed the behavior of this problem. Rather than powering off while the lid is closed, the machine would simply lockup. Screen remains on and laptop powered up, but it seizes to respond. Only recourse is to hold down power button to force a power donw. I see this same lockup when this laptop returns from "Suspend to RAM" which occurs if I hit the Power button during normal operation. With "apm=idle_threshold=100" my laptop doesn't power off or lockup without warning while the lid is closed. Any other suggestions? This doesn't seem to occur anymore in Phoebe's kernel. |
