Hi all, We’re experiencing a recurring issue with the Intel Dual Band Wireless-AC 8265 Wi-Fi module on the **Jetson Nano Developer Kit (JetPack 4.x)**. The chip frequently restarts during operation, leading to **Wi-Fi disconnections** and **runtime kernel errors**. **System Details:** - **Platform** : Jetson Nano Developer Kit - **Wi-Fi Chipset** : Intel Dual Band Wireless-AC 8265 - **Driver** : iwlwifi - **Kernel** : [4.9.201-tegra] - **JetPack Version** : [JetPack 4.5.1] ### 1. **Runtime Logs** We see the following kernel logs during runtime when disconnection occurs (note: this is not every time when disconnection happens): [203.918251] ------------[cut here]------------ [203.957885] WARNING: CPU: 1 PID: 3781 at /home/linux/top\_dir/kernel\_sources/Linux\_for\_Tegra/source/public/kernel/kernel-4.9/drivers/net/wireless/intel/iwlwifi/mvm/rs.c:1212 iwl\_mvm\_rs\_tx\_status+0x2ec/0x8c0 [iwlmvm] [204.185953] Modules linked in: ipt\_MASQUERADE nf\_nat\_masquerade\_ipv4 xt\_conntrack ipt\_REJECT nf\_reject\_ipv4 xt\_tcpudp iptable\_filter nf\_nat\_h323 nf\_conntrack\_h323 nf\_nat\_pptp nf\_nat\_proto\_gre nf\_conntrack\_pptp nf\_conntrack\_proto\_gre nf\_nat\_tftp nf\_conntrack\_tftp nf\_nat\_sip nf\_conntrack\_sip nf\_nat\_irc nf\_conntrack\_irc nf\_nat\_ftp nf\_conntrack\_ftp iptable\_nat nf\_conntrack\_ipv4 nf\_defrag\_ipv4 nf\_nat\_ipv4 nf\_nat nf\_conntrack fuse overlay bnep zram userspace\_alert nvgpu iwlmvm mac80211 ftdi\_sio btusb btrtl btbcm btintel iwlwifi cfg80211 spidev ar0330(O) bluedroid\_pm ip\_tables x\_tables [204.186037] CPU: 1 PID: 3781 Comm: irq/408-iwlwifi Tainted: G O 4.9.201 #1 [204.186039] Hardware name: NVIDIA Jetson Nano Developer Kit (DT) [204.186042] task: ffffffc0eed00000 task.stack: ffffffc0e8674000 [204.186098] PC is at iwl\_mvm\_rs\_tx\_status+0x2ec/0x8c0 [iwlmvm] [204.186150] LR is at iwl\_mvm\_rs\_tx\_status+0x7c/0x8c0 [iwlmvm] [204.186154] pc : [] lr : [] pstate: 60400045 [204.186155] sp : ffffffc0e8677a10 [204.186158] x29: ffffffc0e8677a10 x28: ffffffc0bab80818 [204.186163] x27: ffffffc0bab80ad8 x26: 0000000000000000 [204.186168] x25: 000000000d9afffb x24: 00000000ffffffea [204.186173] x23: 0000000000000000 x22: 0000000000000000 [204.186178] x21: 0000000000000000 x20: ffffffc0de0e15e8 [204.186182] x19: ffffffc0e8677ba0 x18: 0000000000000000 [204.186187] x17: 0000000000000004 x16: 0000000000000000 [204.186192] x15: 0000000000007dac x14: ffffffc0fa3baa00 [204.186196] x13: 0000000000000350 x12: 071c71c71c71c71c [204.186201] x11: 0000000000000605 x10: 0000000000000a10 [204.186205] x9 : 0000000000007d80 x8 : ffffffc0eed00a70 [204.186210] x7 : 00000000000008fa x6 : 0000000000000000 [204.186214] x5 : ffffff80013837e0 x4 : 0000000000000000 [204.186219] x3 : ffffffc0e8677ba0 x2 : 00000000000000ff [204.186224] x1 : 0000000000000001 x0 : ffffff800139925b [204.186230] —[end trace d5ac9942a3b68e71]— [204.241127] Call trace: [204.241187] [] iwl\_mvm\_rs\_tx\_status+0x2ec/0x8c0 [iwlmvm] [204.241239] [] iwl\_mvm\_tx\_reclaim+0x2e0/0x3d0 [iwlmvm] [204.241291] [] iwl\_mvm\_rx\_ba\_notif+0x160/0x1d0 [iwlmvm] [204.241341] [] iwl\_mvm\_rx\_common+0x6c/0x2d8 [iwlmvm] [204.241391] [] iwl\_mvm\_rx+0x7c/0x88 [iwlmvm] [204.241419] [] iwl\_pcie\_rx\_handle+0x270/0x768 [iwlwifi] [204.241444] [] iwl\_pcie\_irq\_handler+0x17c/0x788 [iwlwifi] [204.241452] [] irq\_thread\_fn+0x30/0x80 [204.241455] [] irq\_thread+0x11c/0x1a8 [204.241459] [] kthread+0xec/0xf0 [204.241464] [] ret\_from\_fork+0x10/0x30 [10235.258719] iwlwifi 0000:01:00.0: Queue 16 stuck for 10000 ms.
