Hallo everybody,

We have a fresh new computer installed in June. After running for 3 months without problem it froze.

/var/log/messages has following lines:
1+++++++++++++++++++++++++++++++++++++++
kernel: Eeek! page_mapcount(page) went negative! (-1)

Our system is:

openSUSE 10.3 (i586)
Linux lsmlx8 2.6.22.19-0.2-bigsmp #1 SMP 2008-12-18 10:17:03 +0100 i686 i686 i386 GNU/Linux
gcc (GCC) 4.2.1 (SUSE Linux)

Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz
Motherboard ASUStek P5KPL/1600
Memory 4Gb (2Gb + 2Gb, DIMM0 + DIMM2, 800Mhz)

Reason to run 32-bit SuSE on this monster is because of LabVIEW NI-DAQ which is only 32-bit.

Any idea what these messages are?

Best regards,
Valentin
