Hello,

I am having problem booting 4.9.0-rc6+ on my laptop.

4.9.0-rc5+ works, so not likely hardware issues.


Ubuntu Zesty Zapus

###
gcc-6 with

CONFIG_PCI_QUIRKS=y
CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS=y

After grub, screen turns off. No pre modeset messages. Then system
reboot itself.

When

CONFIG_PCI_QUIRKS not set
CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS not set


System would boot up to: "Clocksource: Switched to clocksource hpet". then loop

'''
Could not create tracefs '' directory
Could not create directory for event
 '''

###
gcc-4.9 system would panic with above settings on.

With them off, setting would boot to login prompt. Only one working terminal.

Login works.
dmesg works

lsmod hangs

Looks like my boot issue might be kvm related. System boots fine with
CONFIG_KVM=m

Thanks

I was able to reproduce the problem with v4.9-rc7+ (commit
88abd8249ee8bcebb98c90e890ea5e342db832af), after git clean -xdf; make
mrproper

Config attached. Need to set CONFIG_KVM=y to reproduce boot issue.

set CONFIG_KVM=y in menuconfig also set CONFIG_IRQ_BYPASS_MANAGER=y, I
dont see config for CONFIG_IRQ_BYPASS_MANAGER in menuconfig. Since it
is hidden I assumed it might be problem, if I set
CONFIG_IRQ_BYPASS_MANAGER=y in config file... did not try building
with only CONFIG_IRQ_BYPASS_MANAGER=y


Thanks

I still can't reproduce, sorry, and the attached panic is yet another
