Platform: Dell Inspiron 3000 CPU: Pentium/55V (quarter-micron) (cira 1997)
The last time I built a working system was March 19, 2002
(4.5-STABLE FreeBSD) This was based on source's I'd cvsup'd
the day before (I think.) I didn't build a system for several
weeks after that, so I'm not sure when the problem was introduced.
When booting, panic occurs in "biodone()" (/sys/kern/vfs_bio.c).
I don't know how to get a stack trace in this situation.
The messages immediately before are:
IP packet filtering initialized, divert disabled, rule-based forwarding
enabled, default to accept, logging limited to 100 packets/entry
by default
panic: biodone: bp 0xc10f2e00 not busy 0
When I "boot -v", I see:
ad0: Success setting UDMA2 on Intel chip
Creating disk ad0
pcic0: Autodetected 5.0V card
panic: bp 0xc10f2e00 not busy 0
On my old, working kernel, the messages around this area (normal boot)
are:
IP packet filtering initialized, divert disabled, rule-based forwarding enabled,
default to accept, logging limited to 100 packets/entry by default
ad0: 6194MB <IBM-DBCA-206480> [13424/15/63] at ata0-master UDMA33
acd0: CDROM <TOSHIBA CD-ROM XM-1702BC> at ata1-master PIO4
Mounting root from ufs:/dev/ad0s2a
A "boot -v", with the old (working) kernel produces:
bpf: stf0 attached
bpf: faith0 attached
IP packet filtering initialized, divert disabled, rule-based forwarding enabled, de
fault to accept, logging limited to 100 packets/entry by default
bpf: ds0 attached
bpf: vlan0 attached
bpf: lo0 attached

I have tried wiping /usr/src (and /usr/obj/*) and re-cvsuping
and I get similar results. I've tried pruning my kernel config
of some things (that weren't causing problems, even if they
weren't working) with similar results.
I am unable to get a dump of the paniced kernel, even when I
reboot with a known working kernel. I haven't tried booting
without my PCMCIA cards installed.
Because my kernel config is now much changed from GENERIC
(I've been incorporating the comments from LINT about various
features I've been playing with), I am using the following
scripts to compare my kernel config with GENERIC:
--- awk script : kernel.awk ---
/^#/ { next }
/^[ \t\f]*$/ { next }
/^[ \t\f]*\#/ { next }
{ print $1 "\t" $2 }
--- end of awk script : kernel.awk -----
The comparison process:
awk -f kernel.awk <GENERIC | sort -u >GENERIC.d
awk -f kernel.awk <INSPIRON3K | sort -u >INSPIRON3K.d
diff GENERIC.d INSPIRON.d
