From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2) Gecko/20010726 Netscape6/6.1 Description of problem: Since I upgrade to RH 7.2 kernel 2.4.7, I cannot poweroff my computer anymore. Under RH 7.1 kernel 2.4.2, powering off worked fine. I tried the following: 1) .config of kernel: CONFIG_APM_REAL_MODE_POWER_OFF=y /etc/grub.conf: kernel /boot/vmlinuz-2.4.7-10world ro root=/dev/hda1 hdb=ide-scsi apm=realmode 2) .config of kernel: CONFIG_APM_REAL_MODE_POWER_OFF=y /etc/grub.conf: kernel /boot/vmlinuz-2.4.7-10world ro root=/dev/hda1 hdb=ide-scsi 3) .config of kernel: # CONFIG_APM_REAL_MODE_POWER_OFF is not set /etc/grub.conf: kernel /boot/vmlinuz-2.4.7-10world ro root=/dev/hda1 hdb=ide-scsi apm=realmode 4) .config of kernel: # CONFIG_APM_REAL_MODE_POWER_OFF is not set /etc/grub.conf: kernel /boot/vmlinuz-2.4.7-10world ro root=/dev/hda1 hdb=ide-scsi In all circumstances, I get the famous "Power down." message asking me to shutdown manually my computer. I search Usenet and found this: http://groups.google.com/groups?q=apm+poweroff.under.linux.2.4.7+alan&hl=fr It might provide some clue. I have not tried taking the 2.4.2 apm.c file and plug it into 2.4.7. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Type "poweroff" at shell or select "shutdown" in gnome logout applet. Actual Results: Computer freezes after showing up on screen "Power down.". CTRL-ALT-DEL does not respond. Expected Results: Computer should poweroff. Additional info: I have decided to be nice and give this problem a low priority, since its possible to shutdown the computer manually. But its annoying and my home server is expected to shutdown after 22h00 and restart the next day at 5h55. I liked it when all this was automatic.
I see the same problem (including kernel 2.4.9-13) but this is a normal or even high priority item for us because we operate a sizable cluster which we need to power off automatically if overheating is detected. The cluster dissipates more than 7.5KW in normal operation, so unless it is actually powered off when the A/C fails, the temperature in the room can rise rapidly to equipment damaging levels. It is unreasonable to expect that someone can be summoned within 15-20 minutes at odd hours of the night simply to push almost a hundred power switches. I'd like to see poweroff working the way it used to.
Can you try passing "apm=realmode_power_off" to the kernel commandline (for grub, edit /boot/grub/grub.conf and add it to the line which also has "vmlinuz" on it)?
Tried this in /etc/grub.conf: title Red Hat Linux-up (2.4.9-13 for World) root (hd0,0) kernel /boot/vmlinuz-2.4.9-13world ro root=/dev/hda1 hdb=ide-scsi apm=realmode_power_off ...and it failed. However, contrary to the 2.4.7-10 kernel, when the "Power down." message appear, CTRL-ALT-DEL does work to reset the machine. In this test, the APM was built as a module and no, I have not forgotten to load it before performing the poweroff. Where are all the apm options documented? I would like to know why you believed that realmode_power_off is a valid token. Finally, on a different topic: Are you guys aware that the Mozilla version you ship with RH 7.2 (Mozilla 0.9.2) cannot show up the https://bugzilla.redhat.com/bugzilla website? Pass the comment through your organization; I believe that an updated Mozilla should be made available on your ftp site.
I replace the 2.4.9 apm.c file with the version provided by 2.4.2, as I read in a thread with Alan Cox on the web, but it did not work. BTW, I checked the source code and found out how you came out with the apm=realmode_power_off.
Since RH 8.0, poweroff worked again. I guess that it was a fluke with the RH 7.2 kernel... You may close this bug report if nobody else is interested. I am not anymore.
