Hello all,
Can anyone throw any light on this, it happens about 5 times a day :(,
but does not always immediately crash the machine, but usually.
I got the same messages with the previous kernel (2.6.18-1.2798.fc6)
Also, the kernel is NOT tainted.
TIA:
Albert.
PS. What is DWARF2 - a better version than DWARF :(
