Subject2.4.5-ac7 oops kswapd
Hello

On my 2.4.5-ac7 SMP regularly I get something like this. Always on kswapd
(pid 3) process.

oceanic:~$ free
total used free shared buffers cached
Mem: 1028488 1024392 4096 52 181064 668876
-/+ buffers/cache: 174452 854036
Swap: 527016 38368 488648

If it was fixed on ac9 - sorry.


ksymoops 2.4.0 on i686 2.4.5-ac7. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.5-ac7/ (default)
