Description Red Hat Bugzilla 2004-09-10 17:52:15 UTC
celestica3, running this kernel:
[root@celestica3 ~]# uname -a
Linux celestica3.lab.boston.redhat.com 2.6.8-1.528.2.10 #1 SMP Wed Sep
1 04:42:30 EDT 2004 ia64 ia64 ia64 GNU/Linux

Doesn't seem to be detecting its serial port.

I don't know anything about this machine.  It could be the thing
that looked like a serial port in the back really isn't.  But I 
thought I better file this so someone who knows for sure can check.

I was trying to use this machine as a terminal server to another
box to capture some output.  dmesg output shows the 8250 banner
loading but no ttyS0 being detected. 

I checked on a McKinley SDV / Tiger SDV box and its serial ports
_were_ detected.

So this can be rejected if it's discovered the thing that looks like
a serial port really isn't or if nobody cares :)

They could require ACPI discovery like the HP serial ports, in which
case... yuk. :)

Comment 2 Red Hat Bugzilla 2004-11-01 20:23:22 UTC
hmmm, rhel3 is on the box now and it apparently detects a serial port:

[root@celestica3 root]# dmesg | grep tty
ttyS0 at 0x03f8 (irq = 44) is a 16550A

[root@celestica3 root]# setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 44

So indeed this could be a bug. I'll try the latest rhel4 kernel.



Comment 3 Red Hat Bugzilla 2007-07-30 02:59:41 UTC
no activities since 2004-11-01, closing it..,
please re-open if it is reproducible with the recent rhel4
