Re: MIPS kernel snapshots - 2.6.25-rc5

I just tried the kernel on O2. The kernel boot but I get this oops while
executing /etc/init.d/* scripts:

CPU 0 Unable to handle kernel paging request at virtual address 0000000000000000, epc == 0000000000000000, ra == 0000000000000

Code: (Bad address in epc)

BTW, if you add support for r8169 kernel module, I would made more test
on these kernels.

Thanks,
