I had a closer look at sources, asm etc
and found that the segfault happens in
include/linux/list.h:88 next->prev = prev;
called via
__list_del_entry
list_del_init
drivers/base/firmware_class.c:452: list_del_init(&buf->pending_list);
so buf->pending_list->next seems to be NULL and is used without being checked.
pending_list should have been initialized in __allocate_fw_buf
but since this SEGV does only happens sometimes,
it indicates a race-condition somewhere
