Frequently Asked Questions

1

What hardware or driver path is relevant to this issue?

The issue is in the Linux kernel ROHM BU27034 IIO light sensor driver. Systems without that driver or sensor path in use are not indicated by the provided information as affected.

2

What condition triggers the excessive delay?

The delay can become effectively infinite when reading the sensor integration time fails and the resulting error code is used to calculate the sleep time.

3

What does the fix change?

If the integration-time read fails, the corrected code uses the smallest integration time as the fallback delay rather than calculating a delay from the error code.

4

Which Ubuntu kernel package families are listed?

The listed packages are ubuntu/linux-riscv, ubuntu/linux-realtime, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-azure-fde, ubuntu/linux-gke, ubuntu/linux-hwe-edge, and ubuntu/linux-gkeop.
