Description Tim Wright 2009-11-13 22:04:54 UTC

Gentoo 2.6.0-r5 crashes with a BUG in net/core/dev.c. This is the same issue reported in http://www.ultraviolet.org/mail-archives/iscsitarget-devel.2009/msg00090.html and occurs because the code wrongly calls sock_release() on the netlink socket rather than using netlink_kernel_release(). There's a simple patch fix at http://www.ultraviolet.org/mail-archives/iscsitarget-devel.2009/msg00108.html which 100% resolves the problem for me.

Reproducible: Always

Steps to Reproduce:
1. Install current 2.6.30-r5 server gentoo config (in VMware as it happens).
2. emerge iscsitarget
3. /etc/init.d/ietd start; poweroff


Actual Results:  
Kernel trips the BUG_ON described above.

Expected Results:  
Normal shutdown.

I created an overlay portage area and rebuilt with this extra patch and it solves the problem.

Diff against the portage /usr/portage/sys-block/iscsitarget tree to add the patch that fixes this problem.

Could you test if the newest iscsitarget in portage fixes this for you?
