I have a small busybox userland that works fine with 2.4.2 kernel, but failed with the latest 2.4.8 kernel. The symptom is that it is stuck at the following prompt: ================ .... Kernel command line: console=ttyS0,115200 ip=bootp .... Freeing unused kernel memory: 4k freed Algorithmics/MIPS FPU Emulator v1.4 serial console detected. Disabling virtual terminals. init started: BusyBox v0.51 (2001.07.18-06:43+0000) multi-call binary Please press Enter to activate this console. ================ A simple test shows the console is still working, i.e., pressing a key *does* generate an interrupt and ISR *does* read the correct char value. I really cannot think of anything else that might make busybox stuck here. Any clue? Anybody else is using busybox with more recent kernels? Jun
