[linux-sunxi] Occasional crash on Cubieboard 2

Hi all, I am running a 5.19.1 kernel on a cubieboard and occasionally get the crash below. Does anyone here have any pointers for me as to what may be going wrong? thanks Torsten [ 5826.086429] Unable to handle kernel paging request at virtual address e975ebf8 [ 5826.093658] [e975ebf8]

looking to the wrong part or the regulator is rounding the value I would say. Any comments? regards Torsten sam...@sholland.org schrieb am Mittwoch, 20. Juli 2022 um 05:24:27 UTC+2: > Hi Torsten, > > On 7/19/22 3:44 AM, Torsten Beyer wrote: > > fantastic - I have built a kernel with

Re: [linux-sunxi] Kernel crash in "cpu_freq"

Hi again, I believe I found the place. Can you confirm that changing the microvolts OPPs in "arch/arm/boot/dts/sun7i-a20.dtsi" is the right place for upping the microvolts for lower frequencies? cheers -tb Torsten Beyer schrieb am Montag, 18. Juli 2022 um 09:26:58 UTC+2: > Hi S

Hi Samuel, am stuck trying to figure out how to increase the voltages. Can you point me to some documentation or quickly explain how I would do that? regards Torsten sam...@sholland.org schrieb am Samstag, 16. Juli 2022 um 06:16:16 UTC+2: > Hi Torsten, > > On 7/13/22 3:18 AM, Tors

[linux-sunxi] Kernel crash in "cpu_freq"

Hi all, I am trying to debug a bug on an open source air navigation box for gliders called openvario . It is based on a cubieboard (A20) plus some additional serial connections and an optional sensor board for various flight related pressures. System runs
