Well some good news: the USB-related crash went away after I reverted the NTFS driver to the previous version used in 374_583.
Since that module gets loaded even when you don't have an USB disk plugged in, there's a chance it might also explain the random crashes experienced by people even without a USB disk plugged in.
I'll try to upload a new test build with this fix in place before heading to bed.
BTW, that issue also affects the RT-AC56U (which is what I just debugged this on).
I uploaded alpha 8:
This build is back to all the binary blobs and wireless files of 374_4561, however the NTFS driver (ufsd.ko) has been reverted to the version from 374.583. This resolved the USB disk related crashes for me.

Please give this a try, even if you did not have a USB disk plugged in. There's a chance that it might still be responsible for some of the other reported random crashes, since that module was still being loaded by the firmware even while there was no disk using it. I'd like confirmation if that was the case or not. If it is, then I'll notify Asus about the results.
Mine is a AC68R, will I still be able to use the alpha8 build just posted?
So if Guest Network is not the common factor, how about everyone having 5ghz enabled?
This was in the 4432 Release Notes -- so maybe something broke here and impacting everyone and not just EU users?:
5. Supported EU 5Ghz DFS channel.
whitey019 said:One thing to note that I just thought of is, I never flashed to 4422. I went straight from 583 to 4561, because so many of you had immediate problems with 4422. I don't know if somehow this could be an issue and that something residual could be leftover from 4422, some new flag, setting, variable, etc. I'm doubtful myself as it sounds like everyone can flash back to working FW without issue, but I though I'd mention it anyhow.
Hi RMerlin! The RT-AC68U Alpha 7 build has been working better with my iPhone 5S. I use the 5GHz band and throughput and connection has always been inconsistent. Uploaded Alpha 7 and throughput has been consistent higher and connections more reliable. What did you do to 5 GHZ in Alpha 7??
With my AC56U, I normally don't use a usb drive in the router....but i plugged one up and it worked fine with no issues. Yes it was NTFS. I even enabled SAMBA and copied some files to an from it just fine.
It has been 1 day 16 hours now since i upgrade stock firmware to _4561. And it has been 2 hrs since I tried the usb disk.....and no issues to report.
I disabled my 5ghz as a test, I had reboot overnight.. so eliminated that one.
My guest leaves my house tonight, iPhone user, so I will be able to test the Guest theory soon.
I still wonder if Whitey has a theory:
So looks like the USB-related crashes and the random crashes are two separate issues.
I'm running out of ideas now as to what else I could downgrade. This will probably have to be addressed by Asus.
