On my Tinderbox machine (similar in operation to pointyhat), I was building packages for 4.10-RELEASE and 5.2.1-RELEASE, and the machine panicked. This is a single-CPU Pentium 4 with 2 GB of RAM. The drive being used for builds is a Maxtor SATA drive connected to a Promise SATA controller. Here is the manually transcribed panic and trace: Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x1c fault code = supervisor write, page not present instruction pointer = 0x8:0xc0533d07 stack pointer = 0x10:0xf5f30a4c frame pointer = 0x10:0xf5f30a58 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 27441 (cpp0) Stopped at vfs_vmio_release+0x1b: lock cmpxchgl %ecx,0x1c(%edx) vfs_vmio_release(dc1fee68) at vfs_vmio_release+0x1b getnewbuf(0,0,4000,4000,1c000) at getnewbuf+0x2b6 getblk(c8103210,7,0,4000,0) at getblk+0x400 cluster_read(c8103210,7,0,4000,0) at cluster_read+0xde ffs_read(f5f30c14) at ffs_read+0x25e vm_read(c3834e58,f5f30c88,c484f880,0,c5877160) at vn_read+0x178 dofileread(c5877160,c3834e58,7,814f000,2f2ed) at dofileread+0x95 read(c5877160,f5f30d14,3,4,293) at read+0x3b syscall(2f,2f,2f,814f000,2f2ed) at syscall+0x287 Xint0x80_syscall() at Xint0x80_syscall+0x1f --- syscall (3, FreeBSD ELF32, read) eip = 0x8064924, esp = 0xbfbfd394, ebp = 0xbfbfd3c0 --- The machine is running: FreeBSD fugu.marcuscom.com 6.0-CURRENT FreeBSD 6.0-CURRENT #0: Sun Aug 29 01:02:18 EDT 2004 root_at_new-fugu.marcuscom.com:/space2/obj/usr/src/sys/FUGU i386 Joe -- PGP Key : http://www.marcuscom.com/pgp.asc
