[Info-vax] Processes hang on USB-access

[Volker Halle]

Jouk,

when looking for the 'current' (hanging) DNA2: IRP address in all of nonpaged pool, I found only 2 occurences of this address:

- UCB$L_IRP in DNA2: UCB
- KPB$PS_IRP of a KPB (Kernel Process Block), which is in state EXE$KP_STALL_GENERAL

Although the SDA> USB SHOW commands in V8.4-2L2 are much more detailled than in previous versions, I can't find anything, which could have caused SYS$DNDRIVER to stall this KPB. DNDRIVER sources are not available.

So the only path to a possible resolution would be a support call to VSI.

Sorry,

Volker.
