| |
Hi,
since a few kernel versions (I unfortunately do not have logs going back more than two months, 2.6.17.13), the serial port on my hp compaq nc8000 is not working any more.
The Linux kernel logs "ttyS0: LSR safety check engaged!" whenever I try to use the port. Googling for this error message suggests that the port may either not be present or broken. I can confirm that both are not the case: The port is present and works fine both on Windows and with an older Knoppix version using a very old 2.6 kernel (I think 2.6.4).
Is it possible that a moderately recent update to the driver is broken? What can I do to debug? What information do you need?
Greetings Marc
