Fwd: Backport RSDL v0.31: Updated RSDL 0.31 backport for 2.6.18.8 &Debian etch x86_64 RSDL 0.31 kernels availability

[Veronique & Vincent]

Hi all,

Here is are the backported RSDL scheduler for a 2.6.18.8 kernel and now also for 2.6.19.7 kernel.

This release includes the original backported 2.6.20.x RSDL 0.31 patch and also has few cleanups to remove unecessary debian make-kpkg files.
This update also includes a small patch to both 2.6.18 and 2.6.19 kernels (http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.20.y.git;a=commit;h=d499ac7a3681e270074e880879d0e0a5ad0849fa).  Would a new stable release of 2.6.18 and .19 including that patch be worth it?

The provided kernels (only for Debian Etch x86_64) might be usefull to make load comparisons between Vanilla vs CK's RSDL scheduler.

Althoug I've been able to backport properly RSDL to a 2.6.18 kernel I'm currently having a bug in the 2.6.19 backported patch.  Help finding that bug would really be appreciated.  2.6.19 BUG in action picture available at http://linux-dev.qc.ec.gc.ca/kernel/debian/etch/x86_64/2.6.19/bug-2.6.19-rsdl-031.jpg

Notes:  There is currently a bug in the backported 2.6.19 RSDL 0.31 kernel.  I've attached a picture of the kernel BUG: call.  Help to trace this bug would really be appreciated since I'm not that much a kernel hacker yet!  Also note that libata PATA is not enabled and that GFS + DLM is enabled.

2.6.20.3 uses the official RSDL 0.31 from CK:
