Will try 2.4.13 and report.
BTW: I'd like to reduce latency in one specific place which bites me most (latencies up to 400000usec) coz I use VESA fb: a BKL in tty_io.c:712 (in do_tty_write()). It looks like we need to move BKL into write() and/or replace it with spinlock. I can't find where that write() func ptr is coming (tracked it to tty->ldisc.write, but failed to find out where that field is assigned to). Somebody enlighten me...
BTW #2: You're doing excellent work, Robert.
