Hi,
I'm having strange lookups on an IBM netfinity 5500 using kernel version
2.3.99pre-3 (the problem exists at least since 2.3.50). The machine freezes
suddenly. The behaviour seems independant of load or network traffic.
Any idea how I could diagnose this problem ?
Configuration :
Linux version 2.3.99-pre3 (root@neo) (gcc version 2.95.2 20000220 (Debian G=
