>Number: 3150 >Category: kern >Synopsis: Cyrix 6x86L-P200+ crashes w/ page fault >Confidential: no >Severity: critical >Priority: high >Responsible: freebsd-bugs >State: open >Class: support >Submitter-Id: current-users >Arrival-Date: Sun Mar 30 19:00:01 PST 1997 >Last-Modified: >Originator: Paul Southworth >Organization: The ETEXT Archives >Release: FreeBSD 2.2.1-RELEASE i386 >Environment: Cyrix 6x86L-P200+ CPU, Mustang R534E motherboard, 128Mb EDO RAM, 3C595, Adaptec 2940UW. CPU serial number is GAKJ3702A. >Description: Error is always a variant on this (below). Sometimes it reboots. Other times it hangs after the final "page fault" is printed at bottom. Other times it hangs after "syncing disks...". Machine stays up for 1-3 hours before crashing. Fatal trap 12: page fault while in kernel mode fault virtual address = 0x10 fault code = supervisor read, page not present instruction pointer = 0x8:0xf01317c6 stack pointer = 0x10:0xf01a8c34 frame pointer = 0x10:0xf01a8c44 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL=0 current process = idle interrupt mask = net tty panic: page fault >How-To-Repeat: Looks like any significant load on the system will cause the crash. For example, starting a dump to tape, compiling libc from source, running glimpseindex on a 750Mb archive. The "current process" field of the panic information varies but is always something innocuous (eg, "idle" or "named", etc). >Fix: Unknown. Exact same configuration is currently running happily with an Intel P5-133 CPU, same setup except for motherboard jumper settings to support the P5-133. >Audit-Trail: >Unformatted:
