it looks like I found the annoying bug which made 2.1.131 unstable:
[root@192 /proc]# uname -a
Linux 192.168.0.3 2.1.131 #2 Mon Jan 18 18:58:22 MET 1999 mips unknown
[root@192 /proc]# uptime
10:15pm up 40 min, 5 users, load average: 17.58, 18.15, 17.53
This is on my DECstation 5000/260 running two "make -j 10 netboot" in
parallel on two kernel source trees. I booted in single user mode, started
inetd manually and opened four telnet sessions :-).
The bug was simple but not necessary obvious: duplicate labels in
r2300_misc.S and r4k_misc.S which, although not declared as such, were
Quick'n'dirty fix: rename those labels.
Please apply the attached patch to r2300_misc.S and experience the
wonderful world of linux-2.1.131 :-).
[As a side note for the not so experienced reader:
patch r2300_misc.S <patch-r2300_misc]
Keep the rubber side down.
