Unable to handle kernel paging request #3242

Closed mstekker closed 4 years ago

mstekker commented 5 years ago

Hi,

I am getting a "Unable to handle kernel paging request" every several hours. The system reboots after the message but stays frozen. Only power off / on brings it up.

What do you have plugged in to the USB ports, or anywhere else?

pelwell commented 5 years ago

This appears to be memory corruption, which invariably has one of two causes - a bad driver, or a low voltage supply. Answering James's question will help to narrow down the former. For the latter, while (or after) running a typical workload, run vcgencmd get_throttled and report the output.

mstekker commented 5 years ago

Thanks for your answers. The UBS dongles are:

Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode) Bus 001 Device 005: ID 148f:5572 Ralink Technology, Corp. RT5572 Wireless Adapter Bus 001 Device 007: ID 0451:16ae Texas Instruments, Inc. (This is a CC2531 ZigBee USB dongle)

Integrated Bluetooth and WiFi are disabled (config.txt / overlays)

vcgencmd get_throttled result: throttled=0x80000

No voltage warnings in syslog.

pelwell commented 4 years ago

No voltage warnings in syslog.

That's no guarantee that voltage isn't an issue if the load changes rapidly - this many dongles should be on a powered hub - but let's assume for now that it isn't. Is it feasible to remove the devices one at a time and test the stability of the remaining system, or does that reduce the functionality so much as to completely break your use cases?

mstekker commented 4 years ago

Hi pelwell,

In the mean time I have tried a powered hub. But with no result. It appears that the issue/exception is not happening with the CC2531 dongle disconnected. Even when the other devices are directly connected to the PI.

If the CC2531 is connected but no software is polling its data, the system also runs very stable. So I am very sure the CC2531 is causing the troubles - which for me is an issue because the unit should monitor ZigBee devices (for example Philips HUE).

For monitoring ZigBee I use the "KillerBee" Python framework which on it's turn is using "PyUSB" to poll the CC2531. PyUSB is using / is a wrapper for libusb. So I am afraid there could be an issue in this chain of use regarding to the kernel crash.

pelwell commented 4 years ago

That's a useful result. We can't spend much time looking into an individual driver that (so far) only affects one person (that we know of), but if you can narrow down the issue any further we can see if there are any changes to the driver in newer kernels that migjt help.

JamesH65 commented 4 years ago

@mstekker Did you have any further results or find any solutions?

real3856 commented 4 years ago

Hi @pelwell, I was wondering if you could tell me why a low voltage supply may cause this problem? I also get this problem during power on/off testing too.

pelwell commented 4 years ago

Because below a certain voltage the internal logic of the SoC starts to fail because the operations don't complete in time for the next clock tick.

mstekker commented 4 years ago

@mstekker Did you have any further results or find any solutions? Hi JamesH65,

After testing with several ac adapters, several Raspberries, several active USB hubs, several CC2531 sticks and the newest raspbian kernel updates the problem still exists as today. An Intel NUC with Debian works fine, so I am stuck regarding not enough knowledge about the kernel.

Best regards,

Mart

mstekker commented 4 years ago

Hi, After updating to the newest kernel version, same hardware, the log stays clean from errors and raspbian is working fine for several days now. I do not know what changed, but the problem is solved as by today with the latest kernel / firmware.

pelwell commented 4 years ago

I suspect that a change in dynamic power management in the firmware has fixed it for you.
