Reverting to ``Pigs'' display The problem only exists on my P-II based hardware: ASUS P54E-NP-4 w 2/133 P5's (96MB) works fine. Micronics W6-LI w 2/200-512 Pro's (128MB) works fine. ASUS P2B-DS w 2/350 P-II (256MB PC-100) has this problem. I have been hacking the BETTER_CLOCK and APIC_INTR_REORDER and APIC_INTR_HIGHPRI_CLOCK to no positive benefit. (One combination may have yielded a small improvement, but since I have no way to prove it...).. My thinking is that this a problem with a lock being affected by cacheing. (or along these lines). I also think that the increased clock drift (kern/9974) is closely related to this problem. (and just may be the same problem). johng@pcrd.net -- John Grzesiak -- 603.548.5706 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
