Hi Everyone,
Sorry for the extremely delayed response here. I wanted to let you know
the 18 month support period for Edgy Eft 6.10 has reached it's end of
life. As a result, we are closing the linux-source-2.6.17 Edgy Eft
kernel task. However, Hardy Heron 8.04 was recently released. It would

I have an IBM ThinkPad A22m yielding a similar issue,
the serial port does not respond under Gutsy.
Kernel is 2.6.22-14-generic.
I tried to remove setserial and reboot, then ran the
serial port boucing script, but no luck.
The port works fine under Windows 2000.
Please advise.

I also have a HP nx5000 laptop and experiencing the same issue. I'm currently
running Gutsy (latest updates installed).
After removing setserial and running Matthew's bounce script it worked for me!

Hi everyone,
I can confirm this problem with a HP nx5000 laptop. The "bounce method"
mentioned seems to fix the problem for me, however it is a bit annoying
that the serial port is noch initialized correctly on boot. I'm on
Feisty with kernel 2.6.20-16-generic.

Here's a shell script that accomplishes the work-around. Testing status
of the script is "works for me". Instructions for adding the script to
a system are within the script itself.

Dirk,
Try using a program like minicom to access the serial port. If you
haven't used minicom before, run "sudo minicom -s" to set up the port
parameters like port name, baudrate, framing and flow control.
Another thing to check is the existance of a ttyS0 lock file in
/var/lock. It should be c

Don't know what's going on with my machine. Here is what I have right

I MAY have figured out a work-around. Try the following and see if it
fixes your problem. I am not sure why this problem occurs, but
disabling and then re-enabling the PNP serial port seems to correctly
initialize it. For some reason the newer kernels aren't correctly

Dirk, I've found that my laptop's serial ports are actually ISA-PNP
ports off an LPC bridge. On my system, they appear in
/sys/bus/pnp/devices/00:02. I've attached the output from an ls and
some cat commands. Could you please do the same in dapper to see if
there are any obvious differences?

Hey Matthew,
Below is the output from Dapper Live CD. If I do that in Edgy, I get the
same. (Haven't upgraded the laptop to Feisty yet)
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0

Dirk,
I am running into the same problem on an nc6000 in feisty. When you
boot from the dapper live CD, what is the output of setserial -a for
each of the potential serial ports (ttyS0 through ttyS3)? Perhaps the
more recent kernels are misdetecting the IRQ/io ports for the HP's
serial ports.

Switching off the infrared port in the BIOS helped me getting the serial
port working in Ubuntu again. Maybe that will do the job for you as well

Unfortunately, I can't confirm that. Removing setserial and rebooting
didn't change anything on my machine. The udevd-event is still coming up
during boot up and the serial port still doesn't work.
By the way, when I boot from the Feisty release CD, it's the same thing

I had remove setserial --> sudo apt-get remove setserial

I have the same problem, on a Medion notebook: Often, serial ports don't
work. In these cases the error "ttyS0: LSR safety check engaged!" shows
up in the kernel log, and I get "no souch device". This is pretty
serious if you only have dialup.

Just wanted to post some more info. I had the same issue with a nc6000
and nw8000, however, I now have a nw8440 and the serial port works fine
in Edgy.
I also noticed that dmesg doesn't have the "ttyS0: LSR safety check
engaged!" error anymore.
Sorry I don't have more.
