looks to me like variable size mismatch ? 
 
Swap is "mounted" but never used. Why, I don't know. 
 
 
Steps to reproduce:  
compile kernel for 64bit sparc, and boot.  
swapon /dev/partition_with_swap 
use loads of memory, and see how oom kills your tasks because of lack of 
memory. 
Swap is never touched.

Is this issue still present in kernel 2.6.13?

Comment 2 Adrian Bunk 2005-12-29 04:45:53 UTC

Please reopen this bug if you can still reproduce it in a recent 2.6 kernel.
