OK, this improves things slightly; the first timeout is gone: [ 0.124444] kernel: pci 0000:07:00.1: Linked as a consumer to 0000:07:00.0 [ 0.124592] kernel: PCI: CLS 64 bytes, default 64 [ 0.124621] kernel: Unpacking initramfs...
But the second (longer) timeout is still there, and now has a trace: [ 4.601812] kernel: usb 1-7: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 28.016007] kernel: watchdog: BUG: soft lockup - CPU#4 stuck for 23s!
