Re: HELP 2.4 booting on a serial console (resend)
Ok, I go for 2.2.20, but still can't 1) - compile the stock one ($CFLAGS set to -medlow when using sparc64-linux-gcc : should be -mcmodel medlow, had to patch arch/sparc64/(kernel/|)Makefile, and then plenty of erros like this : extra tokens at end of #endif directive) 2) - get raid stuff work, at least with 2.2.20 kernel shipped with potato Debian distrib (when I'll come to have stock 2.2.20 run , I may try :) Any hint? Thanks anyway G. - Original Message - Please try 2.2 kernels. (2.2.20) As far as i know, Enterprise 2 is a 32-bit machine (correct me if i am wrong). And as 32-bit S/linux is highly unstable, one should avoid it. Many, many people are waiting for the 2.4.x kernels (ip-tables...) for sun-32 Kind regards, Hans

Hi,
I'm trying to get a 2.4 kernel booting on an Enterprise 2 with 2 CPUs.
The trick is that I'm using a serial console, and have no graphical card
inside the box.
When booting (either 2.4.10-smp from unstable Debian or 2.4.14 compiled on
the box itself after d/l from ftp.kernel.org), boot process starts ok :
Remapping the kernel... done.
Booting Linux...
Starting CPU 1... OK
Then stops with no output and sending break doesn't fall back to the {0} ok
prompt. Appending something like serial or console=/dev/ttyS0 doesn't
help.
Any idea anyone?
I can suggest you something.. try booting a non-smp kernel and if
possible a 2.2 series. I noticed some problem using the console port
to monitor the boot process on 2.4 also on i386 machine. I din't
investigate the problem to much since it was more for fun.

Re: HELP 2.4 booting on a serial console (resend)
Let's just make it clearer. 2.2.20-smp works fine on the box (serial boot OK, no unaligned panic either) , but I still can't do any softRaid Stuff. Regarding raid, this 2.2.20 comes from stable Deabian release, and using the raidtools from the SAME debian release won't work. That's why I considered using 2.4.x., and probably raidtools2. I also considered 2.4.x because of vlan support, but that's not a big issue. Now the question : I can work for myself trying to patch 2.2.20 to get raid stuff work (but I think It's gonna be hard because it's already partially patched by debian maintainer) or I could work for anybody willing to boot 2.4.10 via a serial console (Anyhow, I can't beleive that nobody's using 2.4.10 on some Netra boxes. How come they do not have this problem???), and enjoy helping the community :). But for this, I'd need some troubleshooting hints. That's what I asked for in my previous mail...
