Here is the ninth maintenance release for the v2.4.x branch: http://download.gna.org/xenomai/stable/xenomai-2.4.9.tar.bz2
Special note to PowerPC (32/64) users: the FPU management code has been sanitized an awful lot in this release compared to 2.4.8 and earlier for this architecture. Really. Several bugs which may badly break the floating-point registers state "in some circumstances" have been fixed. Therefore I would strongly recommend to upgrade your Xenomai baseline to 2.4.9, and ideally, kernel 2.6/powerpc users should also move their I-pipe support to 2.6.30-2.7-00, or at the very least backport _both_ of the following patches, in that order, to their kernel tree: 1. http://git.denx.de/?p=ipipe-2.6.git;a=blobdiff;f=arch/powerpc/kernel/fpu.S;h=503de51bed94cc2fc4d17b4342885d0329ba5c1b;hp=2436df33c6f4433d7e7f54b88caad6ba570cf3f6;hb=4a9cffba3407f1238646847aad06712d8952a310;hpb=4d121ab41bda8a269c20b0a1077af8f3ef400105 2. http://git.denx.de/?p=ipipe-2.6.git;a=commitdiff;h=0024416dcce817854cbf80eff420b21ef615672c;hp=d0353a6d1b4b4af7f6990dfa27055c799b3756a9 People running a 2.4.25 kernel (the only one officially supported by Xenomai from the legacy 2.4/ppc kernel series) should definitely upgrade to the following I-pipe patch, to close a few important issues, including the FPU ones: http://download.gna.org/adeos/patches/v2.4/ppc/adeos-ipipe-2.4.25-ppc-DENX-2.2-01.patch Panic mode mitigation: This is a PowerPC-related issue only. Other architectures were not affected by those bugs. = You have been warned = Not scared enough? Ok.
