Slackware 14 hangs when restarting (Dell Latitude 6520)
 
Hi all, I installed Slackware 14 on a Dell Latitude 6520, and everything seems to work fine except for restarting.

Code:

shutdown -h now
works fine, but
Code:

shutdown -r now
does not.

The system seems to shut everything down as expected, but it hangs after "Restarting system":
Code:

Broadcast message from root@euler (tty1) (Mon Aug 5 13:34:44 2013):

Google suggested that adding the reboot kernel parameter in lilo.conf can resolve this issue. I tried "apm", "acpi", "bios" and "force", same result.

I've also seen some suggest that using the apm kernel module instead of apci can help, but it appears that apm isn't installed in my kernel. So, before I compile a new kernel I thought I'd double check here. Any other suggestions?

Also, if I do need to compile a new kernel, what's the best way to get the source code? I decided not to include it in the initial install (because, hey, I've never needed it before!). Can I download it via slackpkg, or should I just download the same version from kernel.org?

Thanks!

Your computer may needs reboot quirks. Try to use a newer kernel, or use magic sysrq to reboot at the end of /etc/rc.d/rc.6
Code:

echo b > /proc/sysrq-trigger

Had an acer aspire one that did that, not sure of your problem, but appending reboot=efi to my lilo.conf fixed it. Like I said this fixed my issue, not sure if your dell is having the same issue. According to http://intosimple.blogspot.com/2012/...with-arch.html you can fix it with reboot=pci

Thanks for the suggestion. Unfortunately, this did not work.

I'm pretty sure I tried efi and pci, not sure why I didn't say so in my original post. I'll try again over the weekend, just in case.
