LabVIEW applications that allocate memory using nipalk.sys may occasionally have bugcheck (Blue Screen) errors

A customer has reported that one of their LabVIEW-based applications causes occasional bugcheck (Blue Screen of Death--BSoD) errors. The crash dump stacks vary, the involved process varies (nipalsm.exe, 'Customer Application'.exe), and the reported types vary (SYSTEM_SERVICE_EXCEPTION, ATTEMPTED_WRITE_TO_READONLY_MEMORY). However, all the observed errors involve nipalk.sys and they all seem to involve memory allocation. The error is observed only when the application initializes access to NI-DAQmx for the first time during an OS session. If the application is able to initialize successfully, the error is not observed while the application executes. The root cause of this error is currently unknown.

Workaround:

There is currently no known workaround for this issue.

DMAR: [DMA Read NO_PASID] Request device [06:00.0] fault addr 0xb8441000 [fault reason 0x06] PTE Read access is not set
Linux distributions that enable DMA remapping by default include Ubuntu 22.04 with kernel 6.8 or higher and Ubuntu 24.04.

Workaround:

Modify the Linux kernel DMA remapping configuration as outlined in https://www.ni.com/r/iommu-linux.
