The HW setup seems to run DOS games & Windows with no problems but has been acting up under FreeBSD. An attempt to install linux yesterday ended in a kernel panic using one set of install disks and funny harddisk errors on the other. My basic question is: Are all these problems symptoms of some HW problem I have or are they related to FreeBSD?? My system: - FreeBSD 2.1.0-RELEASE - Hippo15 PCI motherboard with 128k WrThrough cache, Award BIOS - AMD4/120 Mhz CPU - 24MB RAM (mixture of 8MB of 72pin SIMMs and 16MB of 30pin SIMMs on a SIMM converter board) - Onboard 16550 serial, parallel - Old ISA I/O card jumpered to sio2 (a 16450) needed to get UUCP to work reliably. - Tseng ET4000/W32p video in PCI slot - Floppy disk - Conner floppy tape - Soundblaster Pro + CD-ROM (CR562) - 3 IDE hard-drives of varying ages Primary/Master: 1.6 GB EIDE HDD Primary/Slave: 220MB IDE HDD (oldest) Seconday/Slave: 410MB IDE HDD (old) The 1.6GB HDD has: (i) DOS boot partition, (ii) FreeBSD (iii) An extended partition I was planning to install Linux on (iv) OS/2 Boot Manager The other HDDs are used for additional DOS storage + a newspool. The problems I have observed: 1) Dump causes bus_errors when dumping to the third HDD. This is reproducible. putte:~# dump 3uf - /usr/local | gzip -c -9 > /dos_f/ulocal3 DUMP: Date of this level 3 dump: Mon Mar 11 10:40:55 1996 DUMP: Date of last level 0 dump: Sun Mar 3 18:28:49 1996 DUMP: Dumping /dev/rwd0s3f (/usr/local) to standard output DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 35442 tape blocks. DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] DUMP: Broken pipe DUMP: The ENTIRE dump is aborted. Bus error (core dumped) Exectuting the same command sequence and redirecting /dev/null or /home (located on the first HDD) does not give a bus error. 2) System freezes. I have experienced a number of complete system freezes whilst running X. The symptoms are that the system locks completly (although I can still switch VTs and the mouse works) not allowing me to exec any new programs. After a while I either get a reboot or I hit reset. There is not usually any disk activity at these moments. 3) Panic's on shutdown -> vm_page_free: freeing busy page At more or less regular intervals I am getting panic's upon shutting down the system. I have never had this problem before. putte:/var/crash> gdb -k kernel.2 vmcore.2 GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions.
