I have tried recently to get Debian installed on a 100MHz r4000 indy.
I got it to install and boot the base system, but when I upgrade to the
more recent libc6, I get Bus Errors when I run things like "ls". I
understand that this is related to the MIPS_ATOMIC/ll/sc stuff that has
been discussed here lately. So, I tried the fast-sysmips patch. This
changed the Bus Errors to Segfaults.
I also have another indy with a 175MHz r4400. This machine seems to
work fine even without the fast-sysmips patch.
So what's the deal? Are the r4000 and r4400 that different? It's my
understanding that both the r4000 and the r4400 support the ll/sc
instructions. Should I expect bad/broken hardware on the r4000 machine?
