Well, on the upside, 2.95.4 (Debian Woody) seems to work fine, so you don't have to drown yourself in the pit of slow treacle. However, after printing "kgdb <20030806.1101.35> : port =3f8, IRQ=4, divisor =1", it spews out garbage to the serial console (looks like 8-bit data or something). I didn't enable it on the cmd line, just compiled it in ... does that trigger it for you? ----- Degredation on kernbench is still there: Kernbench: (make -j N vmlinux, where N = 16 x num_cpus) Elapsed System User CPU 2.6.0-test3 45.97 115.83 571.93 1494.50 2.6.0-test3-mm1 46.43 122.78 571.87 1496.00 Quite a bit of extra sys time. I thought the suspected part of the sched changes got backed out, but maybe I'm just not following it ... ------ 4/4 split is still being wierd for me (same pattern as before). I think it's just the rc script crapping out which causes the hostname not to get set, or the rootfs to get remounted r/w.
