It has been faithfully doing its job for a couple of years now from 3.0 - 4.7-stable and has never given a problem. I have read man tuning, LINT, and searched the archives on these two errors and really haven't come up with a lot of information. The following lines from lint are sketchy at best. ------------------------- # If you're tweaking this, you might also want to increase the sysctls # "vm.v_free_min", "vm.v_free_reserved", and "vm.v_free_target". # # The value below is the one more than the default. # options PMAP_SHPGPERPROC=201 ------------------------- Could upping PMAP_SHPGPERPROC by 1 actually be that beneficial? And, could removing apm from the kernel have caused the microuptime problem? I am pasting in dmesg system information for reference. ------------------------- FreeBSD 4.7-STABLE #0: Sun Jan 12 13:26:14 EST 2003 jim@locahost:/usr/obj/usr/src/sys/AURORA_OP Timecounter "i8254" frequency 1193182 Hz CPU: Pentium II/Pentium II Xeon/Celeron (400.91-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x652 Stepping = 2 Features=0x183fbff real memory = 536805376 (524224K bytes) avail memory = 519057408 (506892K bytes) Programming 24 pins in IOAPIC #0 IOAPIC #0 intpin 2 -> irq 0 FreeBSD/SMP: Multiprocessor motherboard cpu0 (BSP): apic id: 0, version: 0x00040011, at 0xfee00000 cpu1 (AP): apic id: 1, version: 0x00040011, at 0xfee00000 ------------------------- Regards, -- Jim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
