Subject[Bug 583] New: Enabling Coda with Devfs causes Kernel Panic
http://bugme.osdl.org/show_bug.cgi?id=583

Summary: Enabling Coda with Devfs causes Kernel Panic
Kernel Version: 2.5.67
Status: NEW
Severity: blocking
Owner: bugme-janitors@lists.osdl.org
Submitter: qubex@punkass.com


Distribution: Gentoo 1.4_rc
Hardware Environment: Micron Millenia Transport, P133 (i586)
Software Environment: i586-pc-linux-gnu, posix threads, gcc 3.2.2
Problem Description: Compiling Devfs into kernel is fine. Compiling Coda
into kernel is fine. Compiling Devfs and Coda together is not fine, causes
a kernel panic.
Sorry, I don't have a console - here is what I can see of the error:

<0>Kernel panic: Attempted to kill init!

Steps to reproduce:
Compile Devfs and Codafs into kernel (have not tested as modules.) This
causes kernel panic upon boot.
