Surely if it's already known, we're waiting for an urgent update in the 2.6.21.x branch? I found several commits in the ChangeLog-2.6.22-rc1 file, and one also in the ChangeLog-2.6.22-rc4 file, that mention bug fixes. Who does one have to notify to get this propagated? I installed 2.6.22-rc5 now and it seems to work. Fingers crossed. -- 2. That which causes joy or happiness. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Known problem, I don't remember when it's been fixed but 2.6.22-rc3 (or
later) kernels should not be affected.
ciao,

Just so I don't leave that issue 'up in the air', the kernel had said: checking if image is initramfs...it isn't (no cpio magic); looks like an initrd and then it panicked when it couldn't mount root fs. It looks like that initrd.img image got rebuilt with a newer version of update-initramfs, and that actually made the old kernel (compiled in an older environment) not recognize it. Oh well, an (updated and) recompiled kernel works. -- 2. That which causes joy or happiness. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

How do you mean boot it with -p? Like, enter 'linux215sc -p' on the SILO
prompt?
[a few minutes later :)]
Wow, that actually worked! Now I see output, and the kernel said:
Console: colour dummy device 80x25
Console: switching to mono PROM 80x34
And later the true problem:

And then this doesn't go well with the fact that qla2xxx is used to access

Let's try 2.6.19.2 that used to work... oh, I seem to have demolished its
initramfs image. Somehow.
I wish I knew the explanation for that -p switch :) I can't find it
documented anywhere...

Re: RSC console redirection on a Fire 280R
Looks okay to me. Try booting linux215sc with '-p', hopefully you'll see where it goes wrong.

Re: RSC console redirection on a Fire 280R
Josip, The only thing I know is that the RSC firmware can be buggy. Maybe you can try to upgrade the RSC firmware and the OBP firmware.
