The WARN_ON() backtrace is unrelated to USB - it is due to SCSI calling
vmalloc/vfree with interrupts disabled. People are working on that.
As for this:
May 14 23:57:09 chimera kernel: usb usb2: string descriptor 0 read error: -108
May 14 23:57:09 chimera last message repeated 2 times
It has been reported before and I assume people are working it, but it
would be nice to have confirmation of that...
