This crash happens every time I try to read /dos (my FAT16 mount
point). Note that I usually have /dos umounted due to:
matte: {34} grep dos /etc/fstab
/dev/wd0s1 /dos msdos rw,noauto 0 0
matte: {35}
So I am manually typing "mount /dos" as root before I run swriter3
to try and access the filesystem.
Also note that it doesn't matter if its mounted "ro" or "rw".
The system freezes solid every time.
It is a total lock up requiring the reset button.
I do have a dumb terminal and serial cable but have never tried
remote dubugging as I am an X user with a modem and only two
serial ports and a life! (read: Wife, kids, pet and hence not
much time to look into these things).
I suppose I could detach the modem and try this. A quick run
down on what to do and what to look for would be good. (I have
not used debuggers much....)
Anyway, gobs of information follows: (dmesg output, kernel conf
file and rc.conf)
A few things to note:
- I have most stuff statically compiled but do load linux LKM on
startup.
- My sound card is plug and pray (but properly configured I think...
boot -c then "pnp 1 0 os enable irq0 5 drq0 1 drq1 5 port0 0x220
port1 0x330" followed by "quit")
- Dont worry about the "Invalid field in CDB" on the old clunker
IBM 305MB SCSI disks 'borrowed' from a RS6000 as I dont ever
try/need to boot from them.
- I do worry about "options CPU_DISABLE_5X86_LSSER". Should I ?
- Dont worry about ccd0-3 (which aren't used) as I dont run softupdates
- Dont laugh at my 50MB QUANTUM LP52S. Its from my Amiga 500!!
- I do tend to have as many optimisations on as possible such as
flags 0xa0ffa0ff on my IDE controllers so look at my kernel
conf file carefully!

"If it is true that our Universe has a zero net value for all conserved
quantities, then it may simply be a fluctuation of the vacuum of some
larger space in which our Universe is imbedded. In answer to the
question of why it happened, I offer the modest proposal that our
Universe is simply one of those things which happen from time to time."
