Title: mt7921e wifi fails to resume after suspend Status in linux package in Ubuntu: New Bug description: After resuming my suspended PC, the wifi becomes unresponsive. The only way to get it working again is to do a full reboot. I'm using Ubuntu 22.04 LTS Jammy and my wifi card is: MEDIATEK Corp. MT7921K (RZ608) Wi-Fi 6E 80MHz using `mt7921e` driver. This is what I can see in the logs: kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020] kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020] kernel: mt7921e 0000:02:00.0: chip reset kernel: mt7921e 0000:02:00.0: Message 0000004e (seq 7) timeout kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020] kernel: mt7921e 0000:02:00.0: chip reset failed kernel: mt7921e 0000:02:00.0: Failed to get patch semaphore kernel: mt7921e 0000:02:00.0: Message 80000010 (seq 4) timeout kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT kernel: mt7921e 0000:02:00.0: chip reset failed kernel: mt7921e 0000:02:00.0: Failed to get patch semaphore kernel: mt7921e 0000:02:00.0: Message 80000010 (seq 12) timeout kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020] kernel: mt7921e 0000:02:00.0: Failed to get patch semaphore kernel: mt7921e 0000:02:00.0: Message 80000010 (seq 11) timeout kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020] kernel: mt7921e 0000:02:00.0: Failed to get patch semaphore kernel: mt7921e 0000:02:00.0: Message 80000010 (seq 10) timeout kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020] kernel: mt7921e 0000:02:00.0: Failed to get patch semaphore kernel: mt7921e 0000:02:00.0: Message 80000010 (seq 9) timeout kernel: mt7921_start+0x25/0x70 [mt7921e] kernel: mt7921e 0000:02:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000a address=0x0 flags=0x0020] kernel: PM: pci_legacy_suspend(): mt7921_pci_suspend+0x0/0x340 [mt7921e] returns -110 kernel: mt7921e 0000:02:00.0: Message 40000007 (seq 2) timeout kernel: mt7921_poll_rx+0x4f/0xe0 [mt7921e] kernel: mt7921e 0000:02:00.0 wlp2s0: renamed from wlan0 NetworkManager: <info> [1653237444.7259] rfkill1: found Wi-Fi radio killswitch (at /sys/devices/pci0000:00/0000:00:02.2/0000:02:00.0/ieee80211/phy0/rfkill1) (driver mt7921e) kernel: mt7921e 0000:02:00.0: Firmware init done kernel: mt7921_pci_driver_init+0x23/0x1000 [mt7921e] kernel: mt7921e 0000:02:00.0: ASIC revision: 79610010 I really appreciate someone's help to fix this behaviour.
