| |
i have released the -U4 PREEMPT_REALTIME patch:
http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-U4
this is a fixes-only release, and it is still experimental code.
Changes since -U3:
- crash fix: fix the rtc_lock related crash reported by Bill Huey, the rtc_lock is now a raw spinlock again.
- crash fix: avoid recursion into timer code when PREEMPT_TIMING is enabled.
- crash/printout fix: revert some of selinux's locks back to raw spinlocks. This could fix the problems reported by Mark H. Johnson, Adam Heath.
- build fix: fix the compilation problems reported by Lee Revell
- debug feature: implemented 'print backtrace on all CPUs' on SMP systems, SysRq+L will trigger it.
- build cleanup: restructure the debug config options. This should resolve the build problems and incompatible debug-options problems reported.
- cleanup: move definitions around, turn on generic rwlocks instead of the x86-specific version.
i think all bugs that were reported with logs are fixed in -U4. Please re-report any issue that might remain.
to create a -U4 tree from scratch the patching order is:
http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.8.tar.bz2 + http://kernel.org/pub/linux/kernel/v2.6/testing/patch-2.6.9-rc4.bz2 + http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc4/2.6.9-rc4-mm1/2.6.9-rc4-mm1.bz2 + http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.9-rc4-mm1-U4
