USB Detection problem with kernel 4.4.20 (4.4.15+ works fine) #1633

mypiandrew · 2016-09-11T18:49:28Z

`This concerns a custom compute module board with various USB devices connected through an integrated GL850 hub chip.

I get strange usb errors on a cold boot that result in an FTDI USB-2-UART device often not getting detected correctly. This only appears to happen when using kernel 4.4.20 (maybe 1 in 4 cold boots in a row), but these don't appear on kernel 4.4.15 regardless of how often I cold boot the board.

This doesn't appear to affect any other device on the bus, and the FTDI device is the only device affected by this

Can you identify the exact update which caused this. See:
https://github.com/Hexxeh/rpi-firmware/commits/master

If you click on each commit the end of the url contains a git hash. Run
sudo rpi-update <hash>
to revert back to that version. Report the first version with this error.

mypiandrew · 2016-09-11T19:05:55Z

Will do :-)

Give me some time to work on it this week and I'll get back to you asap

popcornmix · 2016-09-12T12:27:52Z

Can you clarify that 3dec77a63fbe71aea8feaa8ca600e7c723bb3a7b is the first firmware with the bug and 50f4bc47fc16c05c657c6f6f15719e57917f9b81 works correctly?

mypiandrew · 2016-09-12T12:36:45Z

Correct, the problem re-occurred on the next re-boot after the reboot command issued at the end of the update when moving to 4.4.16 and vanished immediately when moving back to 4.4.15 as above

4.4.17 (82d8b8040558ffcfda5a0714400549e819054c28) also has the USB problem FWIW

popcornmix · 2016-09-12T12:54:46Z

Unfortunately that makes no sense 3dec77a63fbe71aea8feaa8ca600e7c723bb3a7b only contained a trivial fix for deinterlace in the firmware with no kernel change.

Can you double check your results?

mypiandrew · 2016-09-12T12:58:16Z

OK, I'll reboot the board 10 times in a row on 4.4.15 and 4.4.16 and report back

Will be tomorrow now as I have to switch task

mypiandrew · 2016-09-12T13:59:13Z

Just for interest I've just done on 4.4.15+ 10 reboot (5 soft 5 power cycles) and all work AOK

Soft reboot (reboot by command line)
1 OK
2 OK
3 OK
4 OK
5 OK

Hard reboot (power off/on)
1 OK
2 OK
3 OK
4 OK
5 OK

Will be a bit more ordered tomorrow

popcornmix · 2016-09-12T15:25:36Z

3dec77a63fbe71aea8feaa8ca600e7c723bb3a7b is 4.4.15
50f4bc47fc16c05c657c6f6f15719e57917f9b81is 4.4.15
4.4.16 didn't come until two commits later.
Can you make sure you are testing the two commits you have referenced.
uname -a will tell you the new kernel version after reboot. Don't run it after rpi-update without rebooting.

mypiandrew · 2016-09-12T16:49:52Z

Does this help?

http://pastebin.com/NNg1WSxJ

I power cycled the between the first two logins' then upgraded and did a command line reboot, then downgraded and again did a command line reboot.

It's very strange...

popcornmix · 2016-09-12T17:01:34Z

But that log updates to e7178c06ac5b527085ceb380aa56f1ed52558ea0 which isn't the revision you said the problem started with.
I want two consecutive firmware hashes, the older without no problem and the newer with the problem so we can investigate exactly what changed.

I suspect the answer will be
6ab8282964b77388e12cc7f5de7c3d7b72cdcf4c last firmware that worked
e7178c06ac5b527085ceb380aa56f1ed52558ea0 first firmware with problem

but we really need to get that confirmed.

mypiandrew · 2016-09-12T17:15:46Z

I'm sorry for the confusing time here. I'm clearly not the best with Git :(

Thanks for explicitly stating what you want me to do, appreciate it

mypiandrew · 2016-09-12T17:41:50Z

You are correct

6ab8282964b77388e12cc7f5de7c3d7b72cdcf4c <= Works
e7178c06ac5b527085ceb380aa56f1ed52558ea0 <= Doesn't work

If there are any "in between" then let me know the numbers and I'll check (I'm clearly hopeless at that part!)

For checking here's the log

http://pastebin.com/CXNHUb7n

Thanks for your help, hope you can fix it

DougieLawson · 2016-09-15T07:25:04Z

I'm seeing a similar problem with a couple of my USB WiFi dongles and with my B+ that has the filesystem on a USB hard drive.

On my A+ the WiFi keeps breaking (usually around 1:00am until 8:00am when I fix it).

Sep 15 08:10:07 aplus kernel: [35066.553872] ieee80211 phy0: rt2800usb_tx_sta_fi
fo_read_completed: Warning - TX status read failed -71
Sep 15 08:10:07 aplus kernel: [35066.553976] ieee80211 phy0: rt2800usb_tx_sta_fi
fo_read_completed: Warning - TX status read failed -108

On one RPi I ended up having to wire it to my network as a I couldnt get any WiFi dongle to run. Both

Bus 001 Device 005: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter

and

Bus 001 Device 005: ID 0bda:8179 Realtek Semiconductor Corp.

failed to work.

They both work OK with BRANCH=next rpi-update (4.4.17) kernel (which is now running on five out of my eleven raspberries).

On my B+ after I'd tried the experimental bootcode.bin to see if I could boot from the hard drive (with just bootcode.bin on the SDCard) I couldn't get it running when I reverted to 4.4.20 #908 so I reverted to 4.4.17 and that's what it's running today.

mypiandrew · 2016-09-15T07:46:31Z

Hey Dougie

I found 4.4.15 was the last that worked for me, in fact I had to back up to 4.1.21 otherwise I hit a problem with concurrent ttyS0 and SPI access.

Would be interested to see the result of lsusb -t on your system as on mine only the 12M device appeared to be affected and not any of the 480M devices.

DougieLawson · 2016-09-15T12:39:49Z

@mypiandrew at the moment I'm not going to do any additional testing. As far as I'm concerned 4.4.20 #908 is poisonous and I won't be going near it until a later version. My B+ runs my webserver and a bunch of other stuff so I'd like it to be a little bit stable.

popcornmix · 2016-09-15T13:36:12Z

@DougieLawson did your problem start with 4.4.16 (e7178c06ac5b527085ceb380aa56f1ed52558ea0) ? If not it is probably unrelated to the original poster's problem and a new issue would be less confusing.

There is a kernel bump to 4.4.21 available with rpi-update.
While I have no evidence that fixes the problem, it may be worth trying.

mypiandrew · 2017-01-18T09:40:53Z

As far as I can tell, this has been fixed as of

Linux raspberrypi 4.4.43-v7+ #948 SMP Sun Jan 15 22:20:07 GMT 2017 armv7l GNU/Linux

I can't vouch for @DougieLawson but I've been running my CM3 with the same setup using the above rpi update and I've not seen a occurrence.
