1136 bytes is larger than 1024 bytes
Hi James,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: b446a2dae984fa5bd56dd7c3a02a426f87e05813
commit: ebc076b3eddc807729bd81f7bc48e798a3ddc477 scsi: elx: efct: Tie into kernel Kconfig and build process
date: 3 years, 2 months ago
config: arm-allmodconfig (https://download.01.org/0day-ci/archive/20240806/202408061721.gfnwpv1W-lkp@intel.com/config)
compiler: arm-linux-gnueabi-gcc (GCC) 14.1.0
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20240806/202408061721.gfnwpv1W-lkp@intel.com/reproduce)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
