Hello,
kernel test robot noticed "BUG:kernel_hang_in_boot_stage" on:
commit: 61595012f28036a58293df5a2ab75f80ca15c327 ("HID: simplify code in fetch_item()")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
[test failed on linux-next/master d61a00525464bfc5fe92c6ad713350988e492b88]
in testcase: boot
config: x86_64-randconfig-076-20241010
compiler: clang-18
test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 16G
(please refer to attached dmesg/kmsg for entire log/backtrace)
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
| Reported-by: kernel test robot <oliver.sang@xxxxxxxxx>
| Closes: https://lore.kernel.org/oe-lkp/202410161448.b4308a5e-oliver.sang@xxxxxxxxx
(
there is not many clue in below dmesg, we tried to rebuild kernel and rerun
tests more, the issue seems quite persistent and clean on parent

:100 100% 100:100 dmesg.BUG:kernel_hang_in_boot_stage
another thing is the config is a randconfig which is uploaded to [1]
we also tried some config based on rhel-8.3, cannot reprodue the issue
if you want us to test some debug patch, please let us know. thanks!
