It looks like your ramdisk is too large. Is it over 4096 (4k) in size? -----Original Message----- From: balaji.ramalingam@philips.com To: linux-mips@oss.sgi.com Sent: 12/7/01 2:36 PM Subject: not getting the kernel prompt Hello, I had been trying to get the linux kernel 2.4.3 on our latest mips core which is mips32 ISA complient. Finally I was able to boot the kernel after facing a lot of issues. But I was not able to get a kernel prompt. I got the below messages ######################################################################## ################## Detected 32MB of memory Loading MIPS32 MMU routines.

Also there is a inittab file with /sbin/agetty entry to take care of the console ttyS0. I'm using the ttyS00 device (COM1) for both printing the debug messages as well as getting the kernel prompt. I dont know where I'm messing up. PLEASE give me some tips. Any help would be greatly appreciated. regards, Balaji Finished kernel_thread; Going to do unlock and cpu_idle Linux NET4.0 for Linux 2.4
