755568 2009-03-11 09:35:00 Just been noticing lately that the computer will just hardlock and become unresponsive.
Mouse light still on (USB optical mouse), nothing on keyboard lights. And screen shows whatever was onscreen when it locked. Killing X is not possible as the keyboard is unresponsive

Specs:
Asus M2N-VM-DVI
CPU: AMD 4800+ x2
2x 1GB Kingston ValueRAM
Seagate SATA harddrives
(above parts just over a year old)

Enermax 425 PSU (maybe 2 years old)

Integrated graphics, I dont have a Pci-e card to play with
OS: Linux (Gentoo)

I havent run memtest or anything else yet. Just seeing if the Linux peoples would have a clue what to check

Incidentally, has locked in both twm and kde in the last 24 hours.
Has locked before today, just not twice in 24 hours

755569 2009-03-11 09:49:00 What BIOS is on it?? Its up to 0905 as of 9/01/09 this year Speedy Gonzales (78)
755570 2009-03-11 10:10:00 Speedy, the bios version won't make any difference - if it was running fine before on whatever version it currently has, then it obviously isn't an issue.

First thing I'd check there would be the memory (i.e. memtest). If the memory's fine, then make sure you are saving the kernel log someplace - it should have some interesting stuff in there about why it hung.

Do the same for the X log - it's entirely possible that it's X that is hanging, not the kernel.

If you have a custom kernel, make sure you haven't turned off all the debugging options. You could also use the software watchdog to help figure out what's happening (or even better a hardware watchdog, if your motherboard has one).

755571 2009-03-11 10:13:00 Does Linux have / use UUID?

If it does, then it will make a diff, as the last version is for

Fix UUID might got lost.

755572 2009-03-11 10:15:00 Speedy, what are you on about? UUID is a *very* generic acronym, can you clarify whatever feature you're trying to describe here? Erayd (23)
755573 2009-03-11 10:16:00 Well if I knew I would tell you.

Thats all it says, on the ASUS site for the BIOS

755574 2009-03-11 10:19:00 Its possible there was a number of things, these would be my 3 main guesses
1) Memory error
2) CPU Overheating
3) Other software issue, potentially driver-related?

Also, if possible, and its happening semi-frequently then login from another box via ssh. When X hangs, see if the box you ssh'd in from can still use the ssh session, or if that froze too :)

755575 2009-03-11 10:20:00 Myth, Chill has a good point about overheating - you may want to investigate that .

Speedy:
Well if I knew I would tell you .

Thats all it says, on the ASUS site for the BIOSThen please refrain from giving advice about stuff you don't understand - it merely confuses the issue .

For your information, UUID normally stands for 'Universally Unique IDentifier' - you may want to read the wikipedia page here ( . wikipedia . org/wiki/Universally_Unique_Identifier" target="_blank">en . wikipedia . org) .
