This node runs all the default drivers that ship with CentOS 5.7 You mentioned Xen in your subject line, but later say CentOS 5.7, what kernel are you using? is that kernel-xen-2.6.18-274.el5.x86_64.rpm or kernel-2.6.18-274.el5.x86_64.rpm or anything else? can you provide some high level description for what does it take to get that crash? Or. Also, could you run with debug prints open and in case the crash still reproduces, send me the kernel log (in case it becomes big, compressed offlist will be fine... also I guess vger.kernel.org drops attachments anyway) You should open libiscsi2 and ib_iser logs, use "echo 1 > /sys/module/libiscsi2/parameters/debug_libiscsi" and "echo 2 > /sys/module/ib_iser/parameters/debug_level" -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
