[Kernel-packages] [Bug 1871143] Re: Kernel crash during USB device enumeration or mounting
Thanks for the reply. TinyUSB runs on the microcontroller board; it is the USB stack implementation used by the software on the board. So it doesn't touch the kernel, by definition. It is behaving in some way that is unexpected to the Linux driver, and causing bad behavior on the part of the driver. It is possible this is a timing or kernel driver state machine. These crashes occur when I reset the board. So the USB device is forcibly disconnected, and then immediately tries to re-enumerate. This is much faster than the usual unplug/replug time you might see, if say, you unplugged a replugged a USB keyboard or USB flash drive. Would a USB trace be helpful to you? I can use a Beagle and get a trace file. Is this the right place to continue discussing this bug, or should it be in some Linux kernel bug system? Thanks. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1871143 Title: Kernel crash during USB device enumeration or mounting Status in linux package in Ubuntu: Incomplete Bug description: Device is an Adafruit microcontroller board running https://github.com/adafruit/circuitpython, using the TinyUSB USB stack: https://github.com/hathach/tinyusb.

[Kernel-packages] [Bug 1871143] Re: Kernel crash during USB device enumeration or mounting
I was able to reproduce the problem after a few tries with the 5.7.0-050700-generic kernel. I then started trying older kernels. It appears the problem started somewhere between 4.10.0 an 4.18.0. But sometimes it takes several tries to reproduce, so I'll continue some ad- hoc bisecting to see if I can narrow it down. For posterity, here is how I'm reproducing. It may take several tries, but it seems to happen about 1/3 of the time. I don't expect you to need to follow all of this for now: Using CircuitPython 5.3.0 on Adafruit Metro M0 board. Connect to REPL and do: >>> import storage >>> storage.erase_filesystem() can cause an immediate kernel crash, or it might be delayed by several seconds. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1871143 Title: Kernel crash during USB device enumeration or mounting Status in linux package in Ubuntu: Incomplete Bug description: Device is an Adafruit microcontroller board running https://github.com/adafruit/circuitpython, using the TinyUSB USB stack: https://github.com/hathach/tinyusb.

[Kernel-packages] [Bug 1871143] Re: Kernel crash during USB device enumeration or mounting
I brought this up on the linux-usb email list and was told it was more likely to be an issue in the filesystem code. In addition, that code (and the USB code) don't expect an MSC USB device to behave badly, and there's no guarantee that if it does, Linux will not crash. In this case, the filesystem changes abruptly out from under the filesystem code. linux-usb thread: https://marc.info/?l=linux-usb&m=159387610928589&w=2 I suppose you can close this now. I wish Linux were more robust about this, but it appears to be a "won't fix" from their point of view. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1871143 Title: Kernel crash during USB device enumeration or mounting Status in linux package in Ubuntu: Incomplete Bug description: Device is an Adafruit microcontroller board running https://github.com/adafruit/circuitpython, using the TinyUSB USB stack: https://github.com/hathach/tinyusb.
