Grub 0.97, CentOS 4.4 based distro
I’m seeing a weird issue.
In an ATCA shelf, installing the OS over the network works fine, until I plug
in a serial cable wired to a serial console server(tested with multiple brands
(MRV,
If there is no serial cable connected,
all works fine
If there is a serial cable and active session
connected and monitoring the serial port, all works fine.
If there is a serial cable but no active
session monitoring the console, then the OS Install hangs(waited days before I
power cycled), resulting in a grub 15 error.
If I change the serial console server
to use hardware flow control, then all works fine, except I can’t login
afterwards, since agetty is using software flowcontrol (I don’t have
control over these settings)
My question is this. Is it
conceivable that this is a grub issue, is it probing the serial port for some
reason? Is there a way to disable this probe, in order for OS installation to
function with software flowcontrol?
Thank you,
Andy
