B). USMDOS OS:
stable linux v2.2.1 trying to run v2.2.7
all s/w pkg about the latest i.e. Mtools v3.9.4, util-linuxi,
binutils 2.9.1.0.24.tar.gz
bin86_0.13.0-4.deb
precompiled libc6-dev_2.0.7t-1.deb
modules insmod'd: loop.o 3c59x.o
daemons running: syslogd, klogd,inetd ---nothing else
kernel configuration: minimal with i586 option selected,
with MTRR not enabled.
with SMP support not enabled.
with no floating pt emulation.
with FAT,UMSDOS and VFAT filesys.
****** Listing of rc.M that I use ******
# Start system log daemon: syslogd
if [ -x /usr/sbin/syslogd ]; then
echo "Starting system log daemon: syslogd"
/usr/sbin/syslogd -m 0
fi
# Start kernel log daemon: klogd
if [ -x /usr/sbin/klogd ]; then
echo "Starting kernel log daemon: klogd"
# NOTE: I have to do all this since the stack trace doesn't right to a file.
, the ksyms aren't available due to the crash on boot,
, the modules dumped,
, To get the kern.oops which isn't the stack trace - I need to
force a kernel buffer flush or else I won't have any data at the
crash.
Once the kernel crashes, the MSDOS filesystem must be repaired.
Then when I reboot to a stable v2.2.1 kernel, it copies the previous
data to a safe area for review whils't the new data is written out
for the next reboot.
cp -p /var/log/kern.oops /root/kern.oops.$$.`date +%s`
cat /proc/modules >/root/kmodules.`date +%s`
cat /proc/ksyms >/root/ksyms.`date +%s`
# force kernel flush of messages
sync
/usr/sbin/klogd -f /var/log/kern.oops -k /usr/src/linux/System.map -c 1
fi
C). booted the linux v2.2.7
NOTE: I had to hand type this data into a file to run through ksymoops.
To do this, I'll be running kernel v2.2.1 which is stable; however,
all the data fed to ksymoops is the previous kernel v2.2.7 crash
data.
****** The shell script I run on the data ******
#!/bin/sh
ksymoops -V -l /root/227/kmodules.227 -k /root/227/ksyms.227 -o /lib/modules/2.2.7/ /root/227/kern.ops >/root/227/kt.1 2>&1
******** The data dump trace *********
Note: the module warning might be due to be having v2.2.1 3c59x loaded
althought the ksyms were dumped by rc.M start script above.
ksymoops 0.7c on i686 2.2.7. Options used
-V (specified)
-k /root/227/ksyms.227 (specified)
-l /root/227/kmodules.227 (specified)
-o /lib/modules/2.2.7/ (specified)
-m /usr/src/linux/System.map (default)
Warning (compare_ksyms_lsmod): module 3c59x is in lsmod but not in ksyms, probably no symbols exported

Thanks for any further info.
PS: kernels v2.2.1, v2.2.5, v2.2.6 run ok.
kernels v2.2.7, v2.2.8, v2.2.10, v2.2.12, v2.2.13 crash like this
all other kernels weren't tried.
BTW, if SMP and/or MTRR is compiled in, then I don't get a stack trace
at all although it defaults to no SMP since I only have one processor.
PS2: Please email me too since I don't subscribe to this mailing list
due to the other lists I belong too.
