firmware ver 10.1-ct-8x-__fW-022-538f0906 crash repeatedly. #156

Open real-t0mg opened 3 years ago

real-t0mg commented 3 years ago

CT firmware keeps crashing shortly after fresh boot. Especially bad when connecting ASUS TUF-506 laptop with RealtekRTL8822CE 802.11ac PCIe Wireless Network Adapter.

hardware: TP-LINK Archer C7 V5 Firmware: OpenWRT 19.07 ath10k_pci_keeps_crashing.txt

I can compile my own openwrt, what can I do to help debug this?

real-t0mg commented 3 years ago

the crashes are getting more frequent and when the firmware "recovers", the connection is slower. It's very frustrating using an ath10k for production. Let me know what I may test to help. Attached dmesg register's messages when failing. ath10k_fails.txt

greearb commented 3 years ago

hello, first crash I decoded looks a bit weird, so I'll likely need to add debugging. I'll look at other crashes to see if they are the same and attach an image for more debugging soon.

greearb commented 3 years ago

If you try older releases (from a month ago or so), does that work any better?

real-t0mg commented 3 years ago

Negative, it happened with older releases too, that's why I kept updating each time I saw new Candela tech firmware was added on the Openwrt commits.

The only thing I've been able to prove is that the combination of Realtek RTL8822CE 802.11ac PCIe Wireless Network Adapter (kernel driver: rtw_8822ce) with ath10k (candelatech firmw or standard firmware) is fatal on my all of my tp-link Archer C7 V5's. The experience was so bad that I opened another bug on realtek realtek rtl8822 bug

I cannot make ath10k crash with my iwilfi (Intel AC wifi) laptops or with my android phones. The only fix I've found is to have the laptop with the rtw_8822ce wifi driver connect to an AR71XX based router (Openwrt 19.07.4 running on TP-LINK 3500) instead of ATH79 based build.

The screenshot below shows the problematic 19.07.4 with no crashes for the past 3 days after making the rtl8822ce wifi card stick to an AR71XX build (ath9k) host. Screenshot_2020-09-14_14-02-19

greearb commented 3 years ago

Do you happen to have some wave-2 ath10k AP that you can test with? I'm curious if it has similar issues or not... Any idea if that realtek wifi NIC works on Linux enough to trigger the same problem?

real-t0mg commented 3 years ago

hi @greearb, I dont have any wave-2 ath10k hardware to validate if it triggers the same crash. The network card is supported in linux for some time now and works fine with ath9k based access points. Its the interaction between the kernel module rtw88_8822ce and ath10k module with OEM or CandelaTech firmware that is fatal for me. I made my 3 TP-LINK Archer C7 V5 crash the same way, just by having the Asus laptop with the Network controller: Realtek Semiconductor Co., Ltd. RTL8822CE 802.11ac PCIe Wireless Network Adapter connect to the ath10k based AP. Guaranteed 5GHz pandemonium.

greearb commented 3 years ago

Can you point me to the specific model number of your NIC? I'd like to get one to see if I can reproduce the problem locally.

fresh reboot, connect asus laptop, immediate crash. Hopefully there's some register info there that is useful to get this addressed. Let me know how I can help.

Please try this firmware. It has some extra debugging that may help me understand the issue. firmware-2-full-community.bin.gz

Send me the dmesg when it crashes...
