- Does anyone else have problems with Linux not correctly "shutting down"
- the 16550? Ever since the kernel has supported a 16550, I have had to
- hard reset the computer after running linux, or it seems that the
- computer "forgets" that the port that contains the 16550, exists. When I
- soft reboot from linux (after doing a shutdown), the CMOS screen shows
- one less serial port (in my case, None), and programs such as OS/2
- refuse to install the COM drivers because they don't see the serial
- port. (I have no term program running under Linux at the time)
-
- I had this problem with beta versions OS/2 early on where it would
- exhibit the same behavior (and still will if I reboot OS/2 while
- running a term program), but a normal shutdown (in the final release of
- OS/2) "correctly closes" the port (ie. the computer is aware of the
- ports existence when the CMOS screen comes up).
-
- Is there code that needs to be added to Shutdown that would relinquish
- control of the port?
- Thanks..
