SCSI miniport problem with IRP_MN_QUERY_LEGACY_BUS_INFORMATION

NTDEV
1

Hi,

I’m getting an crash on W2K SP2 with a kernel debugger reporting shortly
before:

1:*** IopQueryLegacyBusInformation - Driver cdrom returned STATUS_SUCCESS
1: for IRP_MN_QUERY_LEGACY_BUS_INFORMATION, and a NULL POINTER.

This happens when the number of target devices change on a reboot. The
devnode tree looks like it’s been updated with the new targets. The
Microsoft docs on IRP_MN_QUERY_LEGACY_BUS_INFORMATION are pretty much
non-existent. Running with a single scsi target works fine.

WinXP or NT4 do not show the problem.

Any ideas?
