Re: [lkp] [x86/irq] 4c24cee6b2: IP-Config: Auto-configuration of network failed

[Jiang Liu <jiang.liu@linux.intel.com>]

Hi Ying,
	Thanks for reporting this issue. But I couldn't figure
out what's wrong with this commit. And there's no error or
warning messages in the attached dmesg file. Are there other
systems reporting the same issue?
Thanks,
Gerry
