news 来源：原创 2025/5/6 7:58:11

笔记本访问b站，内核打印的调用栈，这里注意，函数是:

iwl_mvm_mac_itxq_xmit

(drivers/net/wireless/intel/iwlwifi/mvm/mac80211.c)

内核版本（下午编译的）：

root@jason:/home# uname -a

Linux jason 6.14.0+ #12 SMP PREEMPT_DYNAMIC Mon May 5 15:51:00 CST 2025 x86_64 x86_64 x86_64 GNU/Linux

笔记本访问b站，内核打印的调用栈，这里注意，网站是iwl_mvm_mac_itxq_xmit:
