Re: auto poweroff - keyboard dependency?
But be warned that if you tell an E150 to power-off you will have great weeping and wailing and gnashing of teeth getting it to restart. Rather drop to OBP and pull the power. Seems to make much more sense to let it drop to the OBP and then type power-off if that's really what's needed. --- James Whatever My niece called me "Uncle Robot" on the weekend!

When I'd typed the 'halt' command as root, the Linux shutdowned and the machine turned off automatically (no 'power-off' needed on PROM prompt). This tends to hit the list once every few weeks. In both sparc and sparc64 the kernel will not power-off systems that are running with a serial console-- instead they are dropped to OBP (2.2.x did not act this way). I believe Pete was going to remove this "safety measure" in sparc a while back but I don't believe it has been done. If you are running a sparc kernel, remove the check for !serial_console if (auxio_power_register && !serial_console) in arch/sparc/kernel/process.c. In sparc64, remove the check if (!serial_console) in arch/sparc64/kernel/power.c. I have a sysctl patch for sparc that allows selection of power-off at halt for serial console systems. Pete did not like this too much, but I believe it is a fair trade-off IFF anyone believes the safety measure should be preserved. The sparc64 arch could benefit from the same. If you aren't up to recompiling a kernel, depending upon version you might be able to type 'power-off' at OBP. Some versions allow this, some require a keyboard with power button to be present. Of coure, you could always reach over and flip the switch, too, if it is not miles away. E
auto poweroff - keyboard dependency?
Hi All, I've compiled a 2.4.25 kernel. When I'd typed the 'halt' command as root, the Linux shutdowned and the machine turned off automatically (no 'power-off' needed on PROM prompt). I plugged out the monitor and the keyboard. Just the UTP patch cables and the power coord are remained connected. I've started the Sparc, and everything worked fine. The dmesg said: "Keyboard: Not present" and "Console: ttyS0 ...". I typed the 'halt' command in a remote shell. But the machine didn't turned off! I had to power off it manually. After this, connected only the keyboard (and not the monitor). The dmesg said: "Sun TYPE 4 keyboard ..." and "Console: switching to colour frame buffer ...". And the Sparc turned off properly after the 'halt' command. Is it a feature? Is it configurable, that the Sparc turns off withuot keyboard too? Thanks in advance, Jana
locking while booting from floppies
I've got a sparcstation 5 that I am trying to install debian on. I am connecting to the sparc with a serial console. I have created the boot floppy from rescue.bin and asked it to boot from the floppy. The sparc starts to boot from the disk that I have made and finally comes up with: floppy0: WARNING disk change called early VFS: Insert root floppy disk to be loaded into RAM disk and press ENTER I insert the root disk and press enter but nothing happens. It just seems to lock up, I can't even send a BREAK to it. Can anyone shed any light on what's going wrong, and more importantly, how I can fix the problem? I hope that someone can help me, and if I can give any more useful info then let me know as its the first time I've ever used a mailing list. thanks in advance, Dan
