Hello, I took the linux kernel 2.4.3 from ftp://ftp.mips.com/pub/linux/mips/kernel/2.4/src/. This kernel was ported for MIPS32 ISA and its supposed to work with all the mips 4kc core. I took the kernel and ported for our Philips processor PR3950, which is based on a mips 4kc core. I have some issues in the reserve_bootmem() & the paging_init() in the arch/mips/kernel/setup.c. Itseems that they fail in the alloc_bootmem (). I commented these functions and got till console_init() to get the print messages on my screen. I got the message as Kernel Bug in bootmem.c Itseems that the functions BUG() has been executed. So is this a kernel bug? I mean is there some problem in the kernel which has been ported or is it something related to improper memory initialization?. regards, Balaji
