------------------------------------+----------------------------------
Reporter: anonymous | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Chaos Calmer (trunk)
Component: kernel | Version:
Keywords: cannot boot;serial8250 |
------------------------------------+----------------------------------
r46548 CC on my TL-WR841Nv8
it cannot boot randomly,sometime looks fine , i think the serial8250 cause
