https://bugzilla.kernel.org/show_bug.cgi?id=197875 Bug ID: 197875 Summary: Processes hang on attempted access of WDC WD30-EZRX 3TB HDD on HP Z420 Workstation Product: IO/Storage Version: 2.5 Kernel Version: 4.13.x Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: SCSI Assignee: linux-scsi@xxxxxxxxxxxxxxx Reporter: chuck.burt+kernel.org@xxxxxxxxx Regression: No When booted under kernel 4.13.x, processes (such as parted, boot-info, gparted, etc) always hang when attempting to run due to a Western Digital Green WD30-EZRX 3TB HDD. Drive works as expected under kernel 4.10.x (even when all other things are the same about the system but only booted kernel is different).
