    Win 10 - BSOD - Attempted switch from DPC -- No obvious reason / app r

    Hello -- My Win10 desktop started BSODing with Attempted switch from DPC mode with increasing frequency (seems like) for unobvious reasons. Wanting some help in identifying the possible issue(s). I've attached the zip file from the collector utility.
    Thanks for the help.

    The zip file you uploaded is empty. Please run DM_Log_collector again and upload the zip file. Check it first, make sure it has data.

    (good) zip added.

    Well duh. - my bad - didn't think to check.
    The most recent BSOD was kmode excp not handled usbh*ci.sys
    I didn't catch what the * was -- either x or e.

    First thing I see is there is a BIOS update available. You have version 2.0.3, version 2.1.3 is available here: Support for XPS 8900 | Dell US

    I see a lot of entries like the following in the eventlog.txt:
    The driver \Driver\WudfRd failed to load for the device SWD\WPDBUSENUM\_??_USBSTOR#Disk&Ven_Generic-&Prod_xD-Picture&Rev_1.02#058F63626479&30#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}.
    What usb devices do you have plugged in? I suggest removing all except mouse and keyboard.

    The 12/30 10:11 dump (and quite a dew of the others) shows a problem with snapman.sys.
    BugCheck 1E, {ffffffffc0000046, fffff801830cd688, ffffb28c8c764400, fffff80a88b72fde}
    *** WARNING: Unable to verify timestamp for snapman.sys
    *** ERROR: Module load completed but symbols could not be loaded for snapman.sys
    Probably caused by : snapman.sys ( snapman+1cf09 )
    This belongs to Acronis Snapshots Manager which is old, dated 7/13/2007. Uninstall it and see if that helps.
