I recently got a new laptop, an Oyster Brahma with a 24mb ram and a P133, and I installed the 2.2 960801. The first error arrived soon : A Fatal trap 9, but I didn't arrive in time to stop the reset because it arrived when the laptop was doing nothing... Infact I was working on one other machine. The reset let the machine started again but after a few moments it stopped again with an error : panic : vrele : negative reference count So I began to think it was a 2.2 sanp problem so I decided to install the 2.1.5, but here arrive the first surprise. The kernel on the disk was not able to find the Cdrom. After a few attempts spent trying some solutions I decide to install from the dos partition... The installation now worked, I made a new kernel and the second surprise arrived after the rebooting ... it found the cdrom (strange things because I only kill some few lines from the GENERIC). But when I was doing the first configurations : Fatal trap 12: page fault while in kernel mode fault virtual address = 0x400 fault code = supervisor read, page not present instruction pointer = 0x8:0x400 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def 32 1, gran 1 processor eflags = interrupt enabled, resume, iopl=0 current process = 141 (csh) interrupt mask = panic: page fault reboot ... When it started again I began to view some logs to try to understand what was happened...but another Fatal trap 12 arrive , similar to the first with only two differences... fault virtual address = 0xff570001 current process = 1741 (less) these are the last boot infos : <bigger>FreeBSD 2.1.5-RELEASE #0: Thu Sep 26 11:42:29 1996 root@myname.my.domain:/usr/src/sys/compile/BRAHMA CPU: 133-MHz Pentium 735\\90 or 815\\100 (Pentium-class CPU) Origin = "GenuineIntel" Id = 0x52c Stepping=12 Features=0x1bf<<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8> real memory = 25165824 (24576K bytes) avail memory = 22740992 (22208K bytes) Probing for devices on PCI bus 0: chip0 <<generic PCI bridge (vendor=1060 device=e891 subclass=0)> rev 176 on pci0:0 vga0 <<VGA-compatible display device> rev 0 on pci0:17 chip1 <<generic PCI bridge (vendor=1060 device=e886 subclass=1)> rev 178 on pci0:18:0 pci0:18:1: UMC, device=0x673a, class=storage (ide) [no driver assigned] chip2 <<generic PCI bridge (vendor=1013 device=1100 subclass=5)> rev 254 int a irq ?? on pci0:23 Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <<16 virtual consoles, flags=0x0> sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16550A sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A lpt0 at 0x278-0x27f irq 7 on isa lpt0: Interrupt-driven port lp0: TCP/IP capable interface psm0 at 0x60-0x63 irq 12 on motherboard fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: NEC 72065B fd0: 1.44MB 3.5in wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <<HITACHI_DK223A-11> wd0: 1031MB (2111760 sectors), 2095 cyls, 16 heads, 63 S/T, 512 B/S wdc1 at 0x170-0x177 irq 15 on isa wdc1: unit 0 (atapi): <<TOSHIBA CD-ROM XM-1402B/1486>, removable, intr, iordis wcd0: 1033Kb/sec, 128Kb cache, audio play, 255 volume levels, ejectable tray wcd0: 120mm data disc loaded, unlocked npx0 on motherboard npx0: INT 16 interface apm0 on isa apm: found APM BIOS version 1.1 WARNING: / was not properly dismounted. </bigger>So... what's happened ? :-) It is safe to turn the laptop on again ? :-) Regards... +-------------------------------------+--------------------+ | Internet: gmarco@masternet.it | ,,, | | Internet: gmarco@fi.nettuno.it | (o o) | | BIX : ggiovannelli@bix.com | ---oo0-(_)-0oo--- | | http://www.masternet.it/dsc/gmarco | Gianmarco | +-------------------------------------+--------------------+
