Hi I am new to uml. At this time, I even can't use the kernel binary and image to start uml. I am using debian sid, the uml version is 2.6.18-1um-2: i386. My host kernel is customized by myself, which is 2.6.19.2 And when I using binary kernel in http://uml.nagafix.co.uk/kernels/kernel32-2.6.20.3 and busybox , I encounter this: VFS: Mounted root (ext3 filesystem) readonly. : applet not found [42949376.460000] Kernel panic - not syncing: Attempted to kill init!

The address where it happened, 0xb7fcc420, smells like a VDSO, which is an area in which I fixed a bug recently. > BTW: I spent hours to find a relative-stable kernel with UML to compile, but > found a lot of then can't be compiled because of a PAGE_SHIFT error and > syscall0 error.

The two errors I encounter are : arch/um/os-Linux/process.c:142: error: expected declaration specifiers or '...' before 'getpid' exist at least in 2.6.16.33 and fixed by your patch(I can't find it now...). Another is fixed by http://lkml.org/lkml/2006/12/4/355 , which exists in 2.6.19.2 . Now I upgraded host kernel to 2.6.20.3, but uml still can't work. Same error. I tried DSL-2.2 too, almost the same output as fc5. I noticed the warning, but puzzled... Is there a version surely can be used now? I am planning to try hacking kernel using UML. Another question: is my version of UML have something to do with this? It's seems like a version string of kernel ( 2.6.18-1um-2: i386 ). Thanks. -- regards, Yang Sheng |

I can reproduce the BUG with the kernel image and filesystem that you used, but not with current 2.6.21-rc4, so I would say that it was a bug in 2.6.19 that has since been fixed. With the configuration of that kernel in 2.6.21-rc3, I can reproduce the signal 4 panic, so that's something that I can chase now. Jeff -- Work email - jdike at linux dot intel dot com |

Thanks! I got it work all right now! I am mainly using it for kernel hacking, so 3-level page table is not important.
