This crash is in core kernel code, which is unlikely to exhibit such a serious bug.
The most likely cause is corrupted memory caused by other drivers. In the light of that, your initial comment that it happened shortly after enabling desk-top effects may be significant. Alternatively, the fact it occurred during scp may indicate a network driver issue. These bugs are extremely difficult to track down. Can you confirm it only occurs with 'desktop effects'? Please attach the files generated by the following commands: dmesg > dmesg.txt lspci -nnvv > lspci.txt lsmod > lsmod.txt A small possibility exists that you may have bad memory. Can you run a memory test to rule this out.
