<jluthra> pivi: thanks for testing it out.
<jluthra> pivi: on SK-AM62 and other boards, without that patch first `arecord` works fine, but second time if we do `arecord` it causes lockup of the CPU and an unserviced interrupt storm on the DMAengine channel for mcasp
<jluthra> this lockup may cause all kinds of issues with other peripherals as well, requiring a hardboot
<jluthra> what i am not sure about is the "change on the DT that seems completly unrelated" on your board..
<jluthra> pivi: can you also confirm that you are running > 1 `arecord` or equivalent on your board before the issue happens?

<pivi> jluthra: we have only one arecord, if I'm not wrong
<pivi> jluthra: here the whole test script we use https://gist.github.com/dolcini/a570adc2e028e9f1ed4129ad85c8c446
<pivi> jluthra: DT is the one you find in mainline kernel
<pivi> jluthra: with this overlay applied https://git.toradex.com/cgit/device-tree-overlays.git/tree/overlays/verdin-am62_dsi-to-hdmi_overlay.dts I was not able to reproduce the issue. without is systematic.
<pivi> jluthra: the actual i2c device at address 0x48 might not even be there, the difference is this overlay
<pivi> jluthra: I might have seen a ghost, but in my few tries if was really systematic. working this this dtbo applied, broken without
<pivi> jluthra: the board is k3-am625-verdin-wifi-dahlia.dts
<pivi> jluthra: we also run alsabat in our CI, but when reproducing on my desk it was just this
