Description jeefoo 2016-01-10 18:18:47 UTC 
Hi,

I tried the newly erleased RHEL6 like linux on a SUN v890 sparc server.
I downloaded image from here: https://oss.oracle.com/linux-sparc/isos/

(In October 2015, ORACLE released a SPARC-sun4v distribucion based on RHEL-6: http://oss.oracle.com/projects/linux-sparc/)

And after booting the cd on my server I got the following error:


Boot device: cdrom  File and args: 
SILO Version 1.4.14 - Rel: 4.0.18.el6
\
Use <TAB> to see valid boot labels or <RETURN> for default action.
Alternatively, type 'halt' to drop back to the OpenBoot prompt.

Thank you for any help,

Comment 1 Anatoly Pugachev 2016-05-19 09:17:47 UTC 
Can you please try with a more recent kernel ? There's was some fix on early boot in arch/sparc tree ( see http://www.spinics.net/lists/sparclinux/msg15659.html ). Or if it just for fun, try debian sparc64 unofficial images. Thanks.
