Issuing a "halt" command unmounts all filesystems and shuts down all running daemons as intended... however, my notebook does not physically power off after the "power down" message. "shutdown -h now" has the same effect. Recompiling the stock kernel with Real Mode APM enabled has no effect. Latest kernel (2.2.17) exhibits the same issue (with and without Real Mode APM support). This behaviour is not exhibited with Windows 98 SE. RH Linux 7.0 was freshly installed. The notebook is a Digital HiNote Ultra 2000 system consisting of the following configuration: - Pentium 166 MHz CPU w/MMX - 48 MB of RAM - 4.3 GB HDD - CD ROM Drive/3 1/2" FDD - ESS Integrated sound card Please let me know if you need any more information from me.
Did you turn on "Use real mode APM BIOS call to power off" (CONFIG_APM_REAL_MODE_POWER_OFF)? On my Sony Vaio PictureBook, the machine sometimes hung on a halt without the option, but not always. I recently turned on the option and perhaps my machine will *always* shut down without crashing, but who knows? There may be more than one problem at work.
jgotts, Turning on Real Mode APM BIOS (CONFIG_APM_REAL_MODE_POWER_OFF) in the kernel has no effect. Issue also present in the virgin kernel 2.2.18.
"poweroff" not "Halt"
