Hi All,

It was something wrong with my last bisect. I did another bisect. I evaluated the one "sometimes boots" with good.

Log:

Code: Select all

commit 0d0b4c866bcce647f40d73efe5e90aeeb079050a
Author: Jiang Liu <jiang.liu@linux.intel.com>
Date:   Mon Jun 1 16:05:12 2015 +0800

    genirq: Introduce struct irq_common_data to host shared irq data

    With the introduction of hierarchy irqdomain, struct irq_data becomes
    per-chip instead of per-irq and there may be multiple irq_datas
    associated with the same irq. Some per-irq data stored in struct
    irq_data now may get duplicated into multiple irq_datas, and causes
    inconsistent view.

    So introduce struct irq_common_data to host per-irq common data and to
    achieve consistent view among irq_chips.

Hi All,

The first bad commit: http://git.kernel.org/cgit/linux/kernel ... eeb079050a

I replaced the following irq files with the old kernel 4.1 irq files:

Code: Select all

~/Downloads/linux-4.2/linux-4.2-nemo$ cp /home/christian/Downloads/linux-4.1/linux-4.1/include/linux/irq.h include/linux/irq.h

~/Downloads/linux-4.2/linux-4.2-nemo$ cp /home/christian/Downloads/linux-4.1/linux-4.1/kernel/irq/proc.c kernel/irq/proc.c
I compiled the RC1 of kernel 4.2 with these old irq source code files today. I'm happy it boots. :-)

Hi Christian
Tested Mate 15:04 and booting normally
Congratulations, you've done a fantastic job well done
I test debian and ubuntu 15.10 later
