I'm using private address ranges on lan and using NAT to reach the outside world from the workstations, I've also set up transparent proxy with oops. The machine based on the Intel DK440LX mainboard, using a 4GB scsi-2 disk and 128Mb of ram with 2 Compaq netelligent PCI, 1 3Com 509B combo ISA, and 1 Digital chip based PCI card. The machine frozes if it gets more than some connection to NAT, and after restart during booting the kernel I see the following displayed : ... SCB Memory Parity Error at seqaddr = 0x1 And several other numbers 5 or 6 times, but I can't read, because the text is shaking (alternately prints the one line and the other) I'v changed memory bank, and changed memory card 2 times ... First time a similar 100Mhz one second time a brand (Memory Technology) 133Mhz one. I have changed the motherboard (same type), but problem still exist. This message only appears at kernel boot time and it won't start at all, just shaking. Before the freeze I can't see any suspicious message. I don't know maybe it it is still a hardware problem (but some other os was working good on this hw config, but I've heard, that bsd is more sensitive for good hw components) or just I'm too lame to set some of the kernel parameters ....etc, but I can't find it (what where and why) Or just hit a bug ? >How-To-Repeat: unpredictable >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
