Dear all: Hi! I'm working on Toshiba TX3927 RISC Processor Reference board.During development I met a problem.Can someone give me some good suggestions? Let me describe the problem in details: TX3927 board cann't boot up via NFS.It will halt at ================================== VFS: Mounted root (NFS filesystem). Freeing unused kernel memory: 44k freed ======================================== and the reset switch on the TX3927 board cann't work anymore. The kernel is linux-2.2.13-20000211.tar.bz2 with Toshiba TX3927 patch, the NFS root file system is declinuxroot-990611.tgz. I've checked /var/log/messages and find sentence like this: authenticated mount request from 192.168.255.202... so I think NFS file system works well.Can someone give me some good suggestions to solve this problem? These are serial port output: ============================= Toshiba Bootloader for TX RISC Reference Kit Ver 000.10 Copyright (c) 1999, 2000 TOSHIBA Corporation TX3927JMR/JMI TX3927 Rev ( 0) CPU Clk 133Mhz, BUS Clk 66Mhz Slot [0] : MEM Base = 0x80040000, MEM Size = 0x00fc0000 FlashROM BFC00000 - BFFFFFFF Find Toshiba TX3927 PCI Controller.
