By the way thanks again for all the help, everyone, especially Kris.
I read all about kernel debugging last night and today and I decided to
make things easier (I hope) I rebuilt today with a fresh GENERIC kernel
and only enabled the following options:
makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols
# To make an SMP kernel, the next two are needed
options SMP # Symmetric MultiProcessor Kernel
options APIC_IO # Symmetric (APIC) I/O
Now I will wait for it to crash.
When it does crash, I am supposed to watch for the "Instruction pointer"
according to
http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/advanced.html#KERNEL-PANIC-TROUBLESHOOTING
Since that is next to impossible to see that unless I sit in the
freezing cold server room and stare at the monitor until it crashes and
hurry up and write it down I am wondering if that is logged anywhere?
Also, I still can't figure out what RAID controller I actually have so I
am not going to upgrade the firmware/drivers unless this crash dump
post-mortem analysis says I should. What do you think?
The following URLs list all the available upgrades for RAID controllers
but dmesg says:
amr0: <LSILogic MegaRAID> mem 0xf0000000-0xf7ffffff irq 16 at device 7.1
on pci0
amr0: <Integrated HP NetRAID (T5)> Firmware D.02.05, BIOS B.01.04, 16MB RAM
amrd0: <LSILogic MegaRAID logical drive> on amr0
amrd0: 34708MB (71081984 sectors) RAID 5 (optimal)
I just don't see that listed here:
http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?locale=en_US&pnameOID=15389&taskId=135&prodTypeId=15351&prodSeriesId=50448&lang=en&cc=us&swEnvOID=54#1158
I even looked at http://www.lsilogic.com/downloads/selectDownload.do
but I don't see a Integrated HP NetRAID (T5) or a LSILogic MegaRAID
listed there either.
Does anyone actually run FreeBSD 4.x on an HP LH3? Does anyone know
what I should download and install? Any help would be greatly appreciated.
Rick
P.S.
I tried to install ddd but
===> ddd-3.3.8 depends on executable: gcc32 - not found
and gcc32 fails to compile for me. If I get time I will post details on
the posts list, if anyone thinks it might be more useful than gdb.
Please advise.
