I'm seeing similar errors on -current on my AMD K6-2 machine: CPU: AMD-K6(tm) 3D processor (400.91-MHz 586-class CPU) Origin = "AuthenticAMD" Id = 0x58c Stepping = 12 Features=0x8021bf AMD Features=0xffffffff80000800 Data TLB: 128 entries, 2-way associative Instruction TLB: 64 entries, 1-way associative L1 data cache: 32 kbytes, 32 bytes/line, 2 lines/tag, 2-way associative L1 instruction cache: 32 kbytes, 32 bytes/line, 2 lines/tag, 2-way associative Write Allocate Enable Limit: 384M bytes Write Allocate 15-16M bytes: Enable I am seeing make or /usr/libexec/cc1 intermittently coredump with SIG 11 or SIG 10 errors when trying to do a buildworld. I wasn't sure if it was because I had flaky hardware or not. -- Craig Rodrigues http://www.gis.net/~craigr rodrigc@attbi.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
