Hey list. 1. So after finally having some time off of work [after a busy couple of months] i have come back to trying to sort out linux-rt on my AMD PHenom II 965 system - which had failed to boot post 3.12.5-rt7 first, i need to make a correction -rt8 DID boot fine and was stable [after one/initial lockup, it never locked again, and obviously booted fine.]. but i figured this out, only after doing a git-bisect on -rt7 to -rt8 ... and never got around to testing -rt8 to -rt9... However, I decided to give 3.14-rt a run - and again - ended up with the machine failing to boot... Next, i decided to revert all three of the patches that you pointed out Sebastion; | timers-do-not-raise-softirq-unconditionally.patch | timer-Raise-softirq-if-there-s-irq_work.patch | timer-rt-Always-raise-the-softirq-if-there-s-irq_wor.patch well, what i actually ended up doing was reverting the first and modifying the 1st patch to revert the other two patches (by changing ../kernel/timer.c section of the original patch). [ i reverted after applying the linux-rt patch, not split queue]; http://pastebin.com/zwsZg9ZM [ninez@localhost ~]$ uname -a Linux localhost 3.14.0-rt1-1-l-pa #1 SMP PREEMPT RT Sun Apr 13 10:44:19 EDT 2014 x86_64 GNU/Linux I've been running 3.14-rt for a couple of hours now and it appears to be stable, thus far - without those patches/fixes applied [and obviously doesn't boot at all with them applied...and as you know - i am not the only AMD user affected by the boot failures...so i am thinking those patches really need to be looked at again, as they cause serious regressions for some of us :\ It also presents a problem because i package linux-rt and how i am supposed to update it, when if i revert these patches, afaict - other H/W may not boot. [wasn't it some i7 machines that failed or something?]... So i am not sure what to do [aside from not updating my packages until the problem is resolved upstream]. 2. Nvidia [and possibly/most likely other out-of-tree drivers] make use or __rt_mutex_init - which apparently has been changed from EXPORT_SYMBOL to EXPORT_SYMBOL_GPL in 3.14 [or 3.13?] (and obviously in 3.12 it was EXPORT_SYMBOL). I had to end up switching nvidia's license to GPL in order to be able to use the driver/modules. I'm not sure what is supposed to happen here, but nvidia should be usable without having to change it's license [since i never had to before, aside from similar situations where symbols where changed to gpl, only to be reverted back, as has happened before]. anyway, I am less concerned about the nvidia issue [im just pointing it out] and am obviously more concerned about being able to sort out the boot failure issues, as afaict - they are caused by changes in -rt9, not upstream. cheerz Jordan -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
