- Glmark2/VKMark perf drop has been observed with off-screen use case, no deviations with system use case.

QCS6490:

- Peripherals not enumerating connected to the USB0 Type-C port
- Intermittent Color corrupted and flickered preview is coming in back to back camera stream iterations.
- Failure with RAM dump collection to SDCard.
- Camera stream is not starting with OV9282 sensor in BPS mode for the 5 MIPI concurrency BPS Mode use case (3 IMX577+ 2 OV9282).
- Bluetooth not enumerating on Industrial Kit
- WPSS subsystem is offline on Industrial Kit
- Device Fails to Reconnect to ADB After USB-C replug During SR Validation on Industrial Kit

IQ8:

- Secure Device Hangs During Crash Dump Collection with Non-Secure APDP
- FPS drop observed during max CSI MIPI concurrency with the RPI IMX577 sensor

IQ9:

- Mass storage device peripheral disconnects/connects on USB1 after few seconds with Interface plus mezzanine.
- Observing %6 increase in CPU for [1080p30 Decode 16 Sessions + AI] use case and GPU ~3% increase for [1080p30 Decode 16 Sessions + AI]
