When smu_i2c_eeprom_init is called on the smu resuming process under sroiv mode, there will be a call trace: [ 436.377690] dump_stack+0x63/0x85 [ 436.377695] kobject_init+0x77/0x90 [ 436.377704] device_initialize+0x28/0x110 [ 436.377708] device_register+0x12/0x20 [ 436.377756] i2c_register_adapter+0xeb/0x400 [ 436.377763] i2c_add_adapter+0x5a/0x80 [ 436.377951] arcturus_i2c_eeprom_control_init+0x60/0x80 [amdgpu] [ 436.378123] smu_resume+0xcc/0x110 [amdgpu] [ 436.378247] amdgpu_device_gpu_recover+0xfb1/0xfc0 [amdgpu] [ 436.378401] amdgpu_job_timedout+0xf2/0x150 [amdgpu] [ 436.378414] drm_sched_job_timedout+0x70/0xc0 [amd_sched] [ 436.378420] ? drm_sched_job_timedout+0x70/0xc0 [amd_sched] [ 436.378430] process_one_work+0x1fd/0x3f0 [ 436.378438] worker_thread+0x34/0x410 [ 436.378444] kthread+0x121/0x140 [ 436.378451] ? process_one_work+0x3f0/0x3f0 [ 436.378456] ? kthread_create_worker_on_cpu+0x70/0x70 [ 436.378464] ret_from_fork+0x35/0x40 This is because smu_i2c_eeprom is not released on gpu recovering. Actually, smu_i2c_eeprom_init/fini are only needed under bare mental mode.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
