system cannot reboot

hi,

it has been more than one years that my archlinux system cannot reboot(HP laptop nx6110, intel i686).


with the help of  these two links

https://bbs.archlinux.org/viewtopic.php?id=124136
https://bugzilla.kernel.org/show_bug.cgi?id=37712

i know that i should change a parameter ".callback = set_bios_reboot" in the kernel.

but i still have several questions

1) is it a bug? if so, why it is still not fixed.
2) are those patches from above links out of date?
3) could someone teach me or give me some links about how to make such patch? because i think this probelm will be not fixed in the next version of kernel, and i will meet some situation after the new kernel update.


thanks for your help.

Re: system cannot reboot

do you have any kernel parameter?

Re: system cannot reboot

You can just set "reboot=bios" on the kernel cmdline. The file you refer to is just a list of quirks given various DMIs.

Because bugs don't get fixed unless they're reported and patched.

thanks.

i changed some parameters, as

cat /proc/cmdline 

BOOT_IMAGE=/vmlinuz-linux root=UUID=fb94e9da-143a-4682-816f-259eb1daf22f ro quiet reboot=bios

and

grep reboot  /boot/grub/grub.cfg
	
linux	/vmlinuz-linux root=UUID=fb94e9da-143a-4682-816f-259eb1daf22f ro  quiet reboot=bios

linux	/vmlinuz-linux root=UUID=fb94e9da-143a-4682-816f-259eb1daf22f ro  quiet reboot=bios

but the system still cannot reboot.

Re: system cannot reboot

If the cmdline param doesn't work then patching the kernel won't either. There's a number of reboot methods. One of them is bound to work.
