After updating glibc-2.3.4.20041102 every boot was terminated by an oop in jfs related kernel functions. The bug occured reproducible while/after the message "* caching service dependencies" was printed. This is what the OOPS looked like Oops: 0000 [#1] Modules linked in: ... CPU: 0 [some registeres] Process rm (pid: 5667, ...) Stack: ... Call Trace: get_UCSname jfs_unlink permission vfs_unlink lookup_hash sys_unlink sys_ioctl syscall_call Code: ... <1> Unable to handle kernel NULL pointer dereference at virtual address 0000008c Oops 2: Process jfsCommit CallTrace txLazyCommit jfs_lazyCommit ... /lib/rescripts/sh/rc-services.sh: line 471: 5668 Segmentation fault ln -snf "/etc/init.d/$1" "${srcdir}/started/$1" The Oops messages were not exactly the same but always in the jfs-parts. Downgrading to glibc-2.3.4.20041021 solved the problem for me. Reproducible: Always Steps to Reproduce: 1. 2. 3.

the kernel doesnt use libc
Please file this at bugzilla.kernel.org, it's an upstream issue
