Hi all,

since quite some time I've tried to find a memory corruption bug on my Indy. I now suspect that the actual cause is a hardware problem and a recent IRIX kernel core dump supports that theory. Just to be on the safe side, could people running Linux on Indys please run something like

find / -fstype ext2 -type f | xargs md5sym

several times and compare the obtained output. Do they differ in any unexplainable way?

Thanks,

Ralf

do you want, that everybody crash their Indys ?

Everybody, who wants to run the find, should umount /proc before doing it. Otherwise the kernel will crash, when the md5sum /proc/kcore happens.

   This device has completely bogus header. Compaq scores again :-|
It's a host bridge, but it should be called ghost bridge instead ;^)

That's what the -fstype ext2 is supposed to take care of :-)

Re: R4600 MIPS/Linux

Does anyone have a running Linux system on the Deststation Tyne R4600 MIPS/133MHz machine?

No, since my Tyne died in late '94 we don't support this machine anymore. It'll take a kernel hacker to bring it back to live.

Re: Kernel support for R4600 MIPS

Quoted 9 lines · Russell E Glaue

Okay, I know that the R4600 (Deskstation Tyne) is supported in the Linux Kernel. I saw it in there while browsing around the MIPS ported code of the latest Linux kernel. I also know that Linux was once successfully compiled for this processor in the 2.0.2x series.

Does anyone know if I will be able to successfully cross-compile a working Linux kernel for the MIPS R4600 processor with the latest Linux source code? I understand that support is not kept up, but is the existing code still in a compilable state?

The R4600 is supported, just not the Tyne machine which the processor is in ...

Hackers wanted.

If someone were to ship me a Tyne, I'd fix the support for it in Linux. And fix the rPC44 while I was at it. :-)
