call trace on shutdown /reboot

[billium]

I updated tinycore on a Pixie boot and now I get a call trace on shutdown. 
(copied core.gz and vmlinuz from the ISO boot and the optional files from ISO/cde/optional)

It works great during use

The orange text displayed:
Killing -o 1411 - o 1410 - o1413
block nbd0: Receive control failed (result -512)
block nbd0: shutting down socket
WARNING: CPU: 2 PID 1411 at kernel/softirq.c:150 0xc0141199
then a list of modules

then some numbers follower by a call trace.

It then just does not shut down.

I does this on all hardware that boots from PXE.

Have I upgraded wrong?

Thanks

Hi billium
Maybe you have some extensions that are not compatible and also need updating?

You've hit a kernel bug, so probably nothing you did. You could try more recent kernels if it bothers you, or trying to find if someone has a patch for it by searching the trace contents.

Thanks for the answers, it is all up to date, and there is not much loaded,  It doesn't bother me that much as the plug is pulled straight after ... just doesn't look as good!
I think the kernel bug is something to do with NBD.
I will check it out when I can, and see if the kernel can be replaced.

NBD now uses export name instead of port number, but I haven't found a way of doing that yet in the kernel command line, so I am still using:

Code: [Select]

APPEND initrd=tinycore/core.gz keymap=qwerty/uk superuser host=tcPixie1 nbd=192.168.3.200:12345  tce=nbd0

Thanks again for TinyCore.
