I recently encountered some odd issues with the version of iastor.sys (PCI\VEN_8086&DEV_2822&SUBSYS_B0001458&REV_02\3&13C0B0C5&0&FA) which is bundled into DriverPack MassStorage 901. But everything went fine when I upgraded this driver to the last version of Intel Matrix Storage (DriverPack MassStorage 903)... So I'm currently waiting for a release of your marvelous DPM903. When is it scheduled to come out?

Thank you for your work and sorry for my english .
