Sporadic GT-AXE11000 reboots due to kernel panic

[nzwayne]

I have two AXE-11000's and both reboot like within 2-5days, as back in previous append. I reported to ASUS and they advised my issue was a wireless issue and try different firmwares. I've tried... Merlin's 386.7_2, 386.7_0, 386.5_2 and ASUS FW_GT_AXE11000_300438649675, FW_GT_AXE11000_300438647875 no resolution to reboots on either unit.
In the last reboot yesterday (no devices attached) syslog went from 27Jul 06:30 (when it crashed) to 5May 01:05 and lots of logs within seconds, frequent broadcom words, then back to 27Jul 07:26 in a gap of 56mins later. I attached the log for those that might be interested, or have ideas. Updated ASUS with this last crash, not heard back yet.

I'm using now for primary household a GT-AX6000 running 386.7_0 then _2 and no issues at all, very happy with this unit & it's performance. My playing on 6GHz halted at present. :-(

Time to test the 386.7_2 release then.

Well, 386.7_2 didn't work then.
Lasted almost 4 days then had two Kernel panics in a row.
At least it came back up without intervention this time.

My reply was to @Forsaken, but if you're having the same issues, have you performed a full reset to factory defaults after flashing the latest firmware first? And, not using/inserting the USB drive you're using for amtm, during the test period?

Just happened , 386.7_2 just restarted my AX86U. Might have to roll back to 386.5 at this point. 5 days uptime.

Now had 14days (so far...) without reboot on my AXE11000, this a first time, by at least 7 days using ASUS code "FW_GT_AXE11000_300438649675". YIPPEE!! Now wishing (dreaming) for the @RMerlin variant (or later) of this release (probably 388 level) in months to come.
| 24days now as of 22:34 20Aug'22.

This makes no sense, Merlin's firmware uses 386_48966 GPL. This is very close to the release number you state.
From what I can see there would be only a minor difference and NOT affect this problem.

Merlin can you comment?

I don't think that's nearly long enough to start celebrating!
When I first got my AX86S, it ran for 31 days before it rebooted.

Merlin can you comment?

I have no idea what changed at the kernel level between these two GPL versions. If a specific fix is involved, then it wouldn`t require a much larget version jump to include it.

386.5_2 just restarted for me so no luck there, 7 day uptime.

I'm having exactly the same issue with AsusWRT Merlin 386.7_2 on GT-AXE11000. I have however noticed that Asus has recently (17/10/2022) posted a 3.0.0.4.388.21224 - so much further along than Merlin. Has anyone tried it yet and checked the kernel panics?

 

[Maksym]

I've just installed 3.0.0.4.388.21224, monitoring.

Just chiming in here... AX86S experienced first random reboot this evening with merlin 388.1. FWIW, I did just add an AC86u as a mesh node with it, and that one is on 386.7_2. I turned off wpa3... will post if it happens again.

Same, still happening on my AX86U on 388.1

 

[alan6854321]

I'm was still getting random reboots on my AX86S running 388.1

The only thing is, I wasn't getting the "Kernel panic - not syncing: BUG!" entries on my syslog server, it just reboots with no comment in the log file.

I've gone back to 386.7_2 now as it seems to reboot less often and at least I can see what happened in the log.

 

[samfisher]

Did this ever get solved? Still on 386.5_2 and still occasionally getting a random reboot after 9-11 days or so.

For me they disappeared with 388.2_2
Latest release (3004.388.4) is still good.

Ugh, auto restart less than 24h uptime with 3004.388.4

I am having the same problem with random reboots. The latest one happened after 16 days today:

Oct  3 10:16:04 RT-AX86U-A4ECD4D-C kernel: bcm63xx_nand ff801800.nand: timeout waiting for command 0x1

I have an RT-AX86U running 3004.388.4. I ran 386.5_2 until recently. However, I experienced random reboots every couple of days to two weeks since last year.

Has there been any work-around or solution? Why doesn't everyone have these reboots?

 

[alan6854321]

Well, that's a nasty Xmas present!
Just had a"Kernel panic - not syncing: BUG!" crash.
The first for many months, and the first ever on 388.5

May  5 01:05:10 crashlog: <4>BUG: failure at kernel/irq_work.c:141/irq_work_run_list()!

Same here, i don't get why they won't fix such a core issue affecting the premium models. I really cannot have this router reboot randomly, unpredictably. I'm ready to give up on ASUS and go to a simpler Switches & PoE AP Setup using Netgear. It's been many months, maybe years? I don't remember even.

I have a GT-AXE11000 and a GT-AX11000 (without the E) and they have the same (latest) Merlin firmwares and virtually identical configuration. The reboots have been plaguing me on the AXE for months, every Firmware. I have since disabled everything, QOS, classification, roaming assistant, TM IPS. Now I feel like i've been getting less frequent reboots I believe, but it still occasionally happens. I turned off reboot scheduler to see how long it will go.

Interesting detail, why does AXE shows Protected Management Frames options, while the AX does not - they're all identically configured with WPA2/WPA3.

On the AXE i have 2.4/5 as capable, and i had 6GHz as required.

I turned 6GHz off now, to see if this or the protected management frames cause this, as someone had suggested a few posts ago.
