read requests while shutdown

Dear All,

I’ve encountered a problem in my filter driver in Win2K. My driver is
attached to partitions, when system shutdown occurs the upper layer sends to
me IRP_MJ_SHUTDOWN, then IRP_MJ_POWER, then a little later a read request
comes. I forward that request down to the lower device object (ftdisk.sys in
my case), ftdisk returns pending and never completes that request. The
system locks. Should I fail all read/write requests after IRP_MJ_SHUTDOWN in
my filter?

Regards,
Max
