Hi,
After tried with SMP with different combination of
debug.mpsafe{net,vm,vfs}, UP kernel, all the same.
Also, I did tune
options MAXDSIZ=3D(2048UL*1024*1024)
options MAXSSIZ=3D(128UL*1024*1024)
options DFLDSIZ=3D(2048UL*1024*1024)
in my kernel. Dont know if this afftects or not. I will try remove
them, and test again.
Thanks,
Rong-En Fan
