[uml-devel] FC3/i386 root filesystem on ford (x64_64) with 2.6.4 kernel: cannot setup LDT

[uml-devel] FC3/i386 root filesystem on ford (x64_64) with 2.6.4 kernel: cannot setup LDT

[William Stearns]

Good evening, Jeff, all,
 	When trying to set up a fc3 i386 root filesystem on an x86_64 uml 
host, we're getting the following error out of FC3 (which did not show up 
in slackware 10/i386):


kjournald starting.  Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
Mounted devfs on /dev
cannot set up thread-local storage: cannot set up LDT for thread-local 
storage

Kernel panic: Attempted to kill init!
  <6>SysRq : Show Regs
Kernel panic: show_regs
...

 	Is this related to the tls libraries (which I've not yet moved out 
of the way)?  I actually booted this with the "ro single init=/bin/sash" 
command line params to try to rename that directory, but couldn't even get 
to a sash prompt.
 	Cheers,
 	- Bill

I don't know why you can't get a sash prompt, but this diagnosis looks easy.

The tls stuff isn't there, so the shell which tried to use it died.  Since you
did init=/bin/bash or something, the kernel paniced when it died.

I've got a good guess why he couldn't get a sash prompt.  The sash binary is 
probably statically linked against the tls library versions.
