What does parameter1 0x4 for bugcheckcode 0x122 mean?

I've got a bsod (on windows 10.0.14393.0) and trying to figure out what happened. Event log says

bugcheckcode 122
bugcheckparameter1 0x4
bugcheckparameter2 0x0
bugcheckparameter3 0xffff8406530bf010
bugcheckparameter4 0xa782390

but I'm already stuck at parameter1 since when I looked at the corresponding bug check code reference page, there they only have listed parameter1 values 0x1, 0x2, 0x5, 0x6, 0x7, 0x8, 0x9, 0xA and 0xB.

Does anybody know where to find information about parameter1 value 0x4?

Later

Following suggestion in a comment by Jamie Hanrahan I am adding a link to the memory dump file dump.zip.

You made a mistake. The 122 is decimal. The hex value is 0x7A. The 0x7A stands for Bug Check 0x7A: KERNEL_DATA_INPAGE_ERROR

The KERNEL_DATA_INPAGE_ERROR bug check has a value of 0x0000007A. This bug check indicates that the requested page of kernel data from the paging file could not be read into memory.
