Subject: Re: [PATCH v3 1/1] pidfd: implement PIDFD_THREAD flag for
 pidfd_open()



Hello,

kernel test robot noticed "last_state.load_disk_fail" on:

commit: aa9c201b150f15cf12e8df8af531b2c74ae1a8fc ("[PATCH v3 1/1] pidfd: implement PIDFD_THREAD flag for pidfd_open()")
url: https://github.com/intel-lab-lkp/linux/commits/Oleg-Nesterov/pidfd-implement-PIDFD_THREAD-flag-for-pidfd_open/20240131-213408
base: https://git.kernel.org/cgit/linux/kernel/git/vfs/vfs.git vfs.all
patch link: https://lore.kernel.org/all/20240131132602.GA23641@redhat.com/
patch subject: [PATCH v3 1/1] pidfd: implement PIDFD_THREAD flag for pidfd_open()

in testcase: boot

compiler: gcc-12
test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz (Ice Lake) with 128G memory

(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@...el.com>
| Closes: https://lore.kernel.org/oe-lkp/202402081434.9e1ded3-oliver.sang@intel.com



The kernel config and materials to reproduce are available at:
https://download.01.org/0day-ci/archive/20240208/202402081434.9e1ded3-oliver.sang@intel.com


as in dmesg in above link:

LKP: ttyS0: 1408: can't load the disk /dev/disk/by-id/ata-SanDisk_SDSSDH3250G_182971800454-part1, skip testing...

we know this should be related with some early issues but we failed to figure
out. so here also attached parent dmesg as dmesg-e0ee7b583f.xz FYI.
