Cold boot ok but restart hangs

[palo]

New install of Xfce 13 on HPa650e
GeForce FX 5500
1GB ram

If I select restart from the logout menu the sequence seems normal to turn off the monitor and the power button light stays on yet disk activity stops and the monitor stays blank. I then force shutdown with the power button and then startup is normal. Selecting shutdown from the menu causes a normal shutdown and it will power back up without problems. Not sure where to go with this and would appreciate any ideas.

I'm having the exact same issue. No ideas yet.

Thanks for the link, unfortunately none of those fix possibilities solved the problem for me. It is happening on my notebook (like the article assumes), a Thinkpad T60 with LENOVO BIOS Version 2.21.
I'm continuing to search around for an answer now, and it helps to know I can search for Ubuntu fixes instead of Linux Mint specifically.

I found this link: http://www.inforbiro.com/blog-eng/ubunt ... t-problem/
which was basically the same fix as the link posted above, except it provided more options to try.
What ended up finally working for me was: GRUB_CMDLINE_LINUX=”reboot=smp”
which is "Reboot by executing reset on BSP or other CPU (only for X86_32)"


Edit:reboot=smp works the best for me of all possible options in that article, providing mostly successful restarts but still with the occasional one that hangs.

Good link - thanks. It did not fix my problem but as I was testing out all the options I discovered what the problem is likely to be I noticed that I was always able to have a restart from the boot manager before logging in but after a login restart would fail. Suspected a ram problem so ran memtest and got 96 fails in the first few minutes sooo thats gonna have to get fixed and then...

Update: After chasing my tail for hours using memtest+ v1.70 that is with the Xfce 32 Maya ISO which reported thousands of errors on test 7 , I tried memtest+ v4.20 and came up clean - I like that one better Back to testing the reboot fudges in grub, I found the most reliable to be GRUB_CMDLINE_LINUX=”reboot=force” (thanks to the link provided by dragline88).

Edit: None of the grub options work all of the time. REISUB does not reboot either.
Still searching....
