Hi,

I have make it work on 2.2.13 and using a serial interface.  What's the
steps to debug a modular driver, how to import the symbol files? Does KDB
have source level debug capability? Thanks.

Regards,

Olive

Best guess, the size of the kdb symbol table is either too small (you
get warnings about invalid initialisers) or too large (uncompress runs
out of room).

kdb v0.6 is old and no longer supported.  Newer versions of kdb use a
different and better method for getting the symbol table.

	I tried to compile kdb functionality into 2.4 kernel
having modutils version "modutils-2.4.0", and patched the
kde source " kdb-v1.7-2.4.0" onto the 2.4 kernel source,
while comiling with "make bzImage", i had the following problems:

kdb is always released as a patch on top on Linus's kernels.  There is
no CVS tree for kdb, it does not make any sense as free standing code.

I can take replacement patches against the standard kernel or patches
against a kdb patched kernel, the latter is probably easier.  Apply the
kdb patch, take a copy of the patched kernel and edit it.  When your
changes are working, diff -ur between (kernel + kdb) and (kernel + kdb +
your changes).  Just tell me which kernel and kdb patch you have changed.

I'm attempting to use kdb 1.5 on 2.2.18 (via the patch kdb-v1_5-2_2_18.gz).=


I'd like to use this in conjunction with the NMI watchdog timer, but it =
appears that some of the
code supporting the NMI watchdog timer may not have been backported from =
2.4 as part of
this patch.  For example CONFIG_UP_NMI_WATCHDOG is used in arch/i386/kernel=
/traps.c
but the full support for the UP NMI watchdog (generating watchdog events =
based on the performance
counters) doesn't appear to be included in the patch.  Also, some of the =
code in traps.c is
conditionally compiled based on CONFIG_X86_IO_APIC_KAO but this doesn't =
appear to be
a valid config option.  Also, the /proc NMI watchdog support appears to be =
missing.

Should I assume that the NMI watchdog feature isn't supported with the =
backport to 2.2, or am I
missing something?  I'm aware that there is a separate NMI watchdog patch =
for 2.2 kernels, but I
don't believe this includes the UP support and it would need to be =
integrated with kdb.

Thanks in advance,

Dave

Please send in plain text, not quoted printable plus html.

kdb for 2.2 does not use the NMI oopser because the standard 2.2 kernel
has no NMI watchdog.  The feature was added in 2.3.20, around October
12, 1999.

Hi,

I am getting errors while compiling the kdb patched 2.4.0 kernel.
gcc = 2.96
modutils = 2.4.0
make = 3.77

I downloaded it only hours back. I can compile just the kernel and use it pretty 
regularly. The output is below.

Thanks
Amit

Thanks, Compiled it.
My binutils were current,
GNU ld version 2.10.90 (with BFD 2.10.0.18)

but had 2 sets of include directory with the one in /usr/local being older, 
removing it fixed the problem.

Regards
Amit

I'm trying to use kdb-v1.5-2.2.18.  However, I've encountered a
mounting problem were my nfs mounts in fstab fail on boot up.
ext2 filesystems mount OK on boot up.  After boot up, mounts of
either nfs or ext2 filesystems hang in the mount(2) function.
Also, umount of an ext2 filesystem hangs.  The system will not
complete either an init to level 0 (halt) or 6 (reboot).
(Multiuser remote access and the system console function OK.)

I'm also getting three oops displays on boot up (digest follows):

Entering kdb (current = 0xc7ac4000, pid 61 [=modprobe]) Panic: Oops
due to panic @ 0xc8026054 [= usb_register_Rc1964387]

Entering kdb (current = 0xc7920000, pid 295 [=modprobe]) Panic: Oops

Entering kdb (current = 0xc6ed0000, pid 574 [=mount]) Panic: Oops
due to panic @ 0xc0129ec8 [= read_super+0xb8]

The last one is the cause of the NFS mount failure.

In the kernel build, I've used the RH 7.0 (2.2.16-22) .config,
configured all new 2.2.17 and 2.2.18 to N, configured kdb, kdb=on,
and use frame pointers.

Has anyone else tried kdb-v1.5-2.2.18?  Anyone experience the same
problem(s)?  Any suggestions concerning the above mentioned mount
problems and oops messages? 

Sincerely,
