Hide Forgot
Hello, I have no idea where the bug is, but the kernel folks will at least have an idea how to debug it. I'm booting my Phoebe install using a boot disk without problems. When starting it with linux root=/dev/hda2 init=/bin/bash or linux root=/dev/hda2 init=/bin/ash I get Kernel panic: attempted to kill init! OTOH, running linux root=/dev/hda2 init=/sbin/init works just fine. Bot init and *sh are dynamically linked (altough bash uses a few more libraries).
Yeah, I've seen this with up to 2.4.20-2.9 (have *not* tested 2.10 yet.)
Still happens with 2.4.20-2.18, FWIW.
2.4.18-19.8.0 works ok on top of Phoebe.
init=/usr/bin/gdb fails init=/bin/ash.static fails They seem to be exiting prematurely. Of note when running init=specially-hacked-strace-that-just-runs-bash: open of /dev/tty fails with ENXIO ioctl()s on stdin fail with ENOTTY Later, *read* of fd 0 fails with EISDIR (?????)
Followup to last comments: If you look at init: [root@nostromo 1]# ls -l fd/ total 0 lrwx------ 1 root root 64 Feb 12 15:22 10 -> /dev/initctl lr-x------ 1 root root 64 Feb 12 15:22 3 -> / lr-x------ 1 root root 64 Feb 12 15:22 4 -> / 3 & 4 are the initrd root. 7.2, 7.3, and 8.0 kernels don't have these fds. These fds certainly sound related to the ENOTTY, EISDIR errors above.
The following patch fixes this for me and looks like the right patch. greetings, Florian La Roche --- linux-2.4.20/init/do_mounts.c.lr Wed Feb 12 22:54:02 2003 +++ linux-2.4.20/init/do_mounts.c Wed Feb 12 22:55:57 2003 @@ -837,6 +837,9 @@ sys_chroot("."); sys_umount("/old/dev", 0); + close (root_fd); + close (old_fd); + if (real_root_dev == ram0) { sys_chdir("/old"); return;
Fix verified in most recent kernel. Resolving as fixed in rawhide.
