Hey list, I've been meaning to post, but alas, I am working three jobs right now (just took on more work) and haven't had a whole lot of free time to investigate my boot problems on linux-rt (-rt9, -rt10, -rt11, -rt13). On 3.12.8-rt11 - i was able to get the kernel to boot via reverting two patches, from the split queue; 'timer-Raise-softirq-if-there-s-irq_work.patch' 'timers-do-not-raise-softirq-unconditionally.patch' (i haven't tried reverting on -rt13, as i haven't had the time to do that). however, while this was enough to boot - my system was unstable. thus i downgraded my kernel back to trusty 3.12.5-rt7 - which works flawlessly for me. Next, I saw the -rt13 release, thinking maybe the boot issue was finally solved [according to the change log], but no - it fails just as before... I tried to add debug to grub's commandline but in the end, it wasn't really helpful. [the last thing shown is something about PnP and then ACPI]; [ 0.255329] pnp: PnP ACPI: found 10 devices [ 0.255330] ACPI: bus type PNP unregistered (which i would normally see anyway.) I might have some time over the weekend (hopefully), to take a closer look - but i thought i would at least notify the list ~ as i saw another user have the same booting problems and he has the same CPU as i do; AMD Phenom 965 X4 [not exactly exotic H/W and every RT release has worked great on my setup, until 3.12.x-rt8. Now, nothing works properly. [note: vanilla 3.12.x kernels boot just fine]. anyway, if anyone has some suggestions - that i could follow up on over the weekend that would be fantastic. cheers 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
