Anyone here still using the Xirrus product line. I have a weird issue with a XR4000 series unit. It fails to boot up. When I connected to the console port I got an error saying.  
“Failed to mount ext2 file system…”  
Any chance this can be fixed in the boot loader?

This is most likely a failed USB drive. If eligible, have you logged a ticket for RMA? If not eligible, it is possible to replace the drive.
