I keep seeing silo errors on sio0 when running at 115200. The UART is a 16550 A (or rather, the port is on board with an 16550 inside one of those little ASICs), and the problem occurs mainly when performing tasks of any kind, especially when changing virtual consoles from and to the X Server. If I simply sit and watch I sometimes get siloes every two to five seconds, sometimes i'm also entirely spared. The system is 2.1.7-stable, and my modem is an ELSA Microlink 33.6TQV. I'd be grateful for hints of any kind, because it sometimes nukes my TCPIP transfers. Thanks - Philipp
