Current from testing here. the same here. I can now even confirm the same problem on a different machine, a dual G4 450, running debian testing. The actual problem seems not to be an infinite loop, but rather a very long loop. IF you wait long enough, it will eventually work. A significant delay (i.e. assumed long loop) is also observed while loading any module. Something like 10 - 15 seconds for every module that I'm loading during startup (ipv6, tulip, dmasound_pmac, ...) The machine is completely frozen during that loop, not even the cursor is blinking anymore. compiling the kernel with gcc 2.95 or 3.0 removes those symptoms. > -- > Earthling Michel Dänzer | Debian (powerpc), X and DRI developer -- - Harald Welte http://www.gnumonks.org/ ============================================================================ Programming is like sex: One mistake and you have to support it your lifetime ** Sent via the linuxppc-dev mail list.
