During installation in graphics mode the serial microsoft mouse works.
But when Linux starts the console mouse drivers, the following error
appears: 'LSR Safety check engaged!', meaning that the UART 16550A
returns 0xFF to a query of the serial device driver which then
concludes that there is some problem. Result: no serial mouse or
whatever device on the serial port will work.
Now I looked for this problem in google and found
as an explanation: a sloppy designed UART 16550A chip...
My question: is there any updated driver somewhere in which this
problem is resolved?
Or is there any parameter that I can apply during start up to prevent
the serial driver from performing this check?
thanks a lot,
