Kernel NFS boot failure

Hi All,

We observe Kernel boot failure while running NFS boot stress test (1000 iterations):
- Linux version 4.7.0 
- am335x-evm (TI AM335x EVM)
- failure rate 10-20 times per test.
Originally this issue was reproduced using TI Kernel 4.4
( git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git, branch: ti-linux-4.4.y)
on both am335x-evm and am57xx-beagle-x15(am57xx-evm) platforms.
This issues has not been reproduced with TI Kernel 4.1 before.

The SysRq shows that system stuck in nfs_fs_mount()

I'd be appreciated for any help or advice related to this issue?

Thanks in advance.
