And for the hppa port of
Debian GNU/Linux I think it's a very good combination of size and
hardware resources. In addition it has built-in remote control
capabilities (see [1]).
Interesting for a remote server with modem access to the serial port.
I've tried it out on my machine, but after entering ESC-(, the serial
line simply freezes up. Maybe a BMC-password is set that should be
cleared.
Can't remember seeing something like this on my c8000s, but I can check
tomorrow.
I did a few tests and when a password was set I always got a "Password:
" prompt when it was needed to enter a password (e.g. after issuing "q"
to end a BMC (admin) session). Not sure what's the reason for your issue.
What did you type in exactly?
I always had to finish the escape sequence with the <Enter> key after
typing in `<ESC>(` and also when escaping from the BMC with `<ESC>)`.
BTW, I use `screen` to access the serial console. Maybe you try with
that tool, too, with e.g. `screen /dev/ttyUSB0 9600,cs8` (`<Ctrl>ak` to
exit).
The firmware version on the tested c8000 is "2.13" and the BMC firmware
revision is "2.32".
And regarding the crashes and instabilities I see, I'm now sure, that
they are coming from the "apt-get upgrade". The original 8 (jessie)
installation works absolutely stable. But after the upgrade, the system
either doesn't boot or it crashes sometime later. This doesn't happen
without the upgrade.
Never noticed a difference in stability for my c8000s depending on the
OS release level, but mostly used rp3440s since I have acquired them. I
can check with a c8000 tomorrow if I notice any differences in behaviour.
I didn't experience any instabilities with the c8000 I tested today.
Like yours it has two 1 GHz PA-8800 dual cores installed.
I really assume that removing the graphics card will be key to stability
for your c8000. This or maybe blacklisting the radeon module with
`modprobe.blacklist=radeon` in the kernel command line.
Cheers,
Frank
