[loongson-dev] kernel boot panic
Hi, all I am porting android to loongson2f, the android file system(froyo) and android linux kernel(2.6.35) was compiled succeed, then I put them to two separate partition of u-disk which was partitioned to ext3, then I start the loongson machine and step into the pmon environment and I typed: load /dev/fs/ext2@usb0/vmlinux.32 g console=tty root=/dev/sda2 rw init=/init rootwait androidboot.console=ttyS0 after which, the penguin logo appeared, and the following info was printed: .. .. .. EXT3-fs (sda2): using internal journal EXT3-fs (sda2): recovery complete EXT3-fs (sda2): mounted filesystem with writeback data mode VFS: Mounted root (ext3 filesystem) on device 8:2. Freeing unused kernel memory: 240k freed Kernel panic - not syncing: Attempted to kill init! By insight into the linux kernel source code, I found that it was the time the kernel mount the filesystem that the kernel panic, but I don't know the exact place the kernel panic. So, in order to find exact point the kernel panic, I want to debug the kernel, I found that a tool called kgdb can debug linux source in source code, but there is not tool corresponding to 2.6.35 or higher linux kernel exist in the official size, so I want to know how did you debug the loongson linux kernel? any suggestion or tips well be greatly appreciated!!! andy -- You received this message because you are subscribed to the Google Groups "loongson-dev" group.

Re: [loongson-dev] kernel boot panic
The kill init message means your init process exit(it should never),it is not kernal fault, try add prints in init source code to find out reason,probably due to illegal instruction,or wrong init.rc李晖 编写：Hi, all I am porting android to loongson2f, the android file system(froyo) and android linux kernel(2.6.35) was compiled succeed, then I put them to two separate partition of u-disk which was partitioned to ext3, then I start the loongson machine and step into the pmon environment and I typed: load /dev/fs/ext2@usb0/vmlinux.32 g console=tty root=/dev/sda2 rw init=/init rootwait androidboot.console=ttyS0 after which, the penguin logo appeared, and the following info was printed: .. .. ..

For illegal instructions,you can add printk in arch/mips/kernal/traps do_ri entrancezhangfx 编写：The kill init message means your init process exit(it should never),it is not kernal fault, try add prints in init source code to find out reason,probably due to illegal instruction,or wrong init.rc李晖 编写：Hi, all I am porting android to loongson2f, the android file system(froyo) and android linux kernel(2.6.35) was compiled succeed, then I put them to two separate partition of u-disk which was partitioned to ext3, then I start the loongson machine and step into the pmon environment and I typed: load /dev/fs/ext2@usb0/vmlinux.32 g console=tty root=/dev/sda2 rw init=/init rootwait androidboot.console=ttyS0 after which, the penguin logo appeared, and the following info was printed: .. .. ..
