Description

新采购了一批机器, dell R730, 网卡Broadcom Corporation NetXtreme II BCM57800 1/10 Gigabit Ethernet, cpu intel e5-2630-v3, 编译后启动时显示kernel panic, lvs三个版本都试过, 都是同样的报错。 用原来的centos6.4内核启动后查看dmesg日志, 有部分内容如下:
UNSUPPORTED HARDWARE DEVICE: Intel CPU model
------------[ cut here ]------------
WARNING: at kernel/rh_taint.c:13 mark_hardware_unsupported+0x39/0x40() (Not tainted)
Hardware name: PowerEdge R730
Your hardware is unsupported. Please do not report bugs, panics, oopses, etc., on this hardware.

是不是内核太老了, 无法驱动新的硬件啊
lvs还是220的内核, 随着现在硬件更新越来越快, 马上lvs就不支持了啊

Research direction

Start by reviewing the reported dmesg trace and the kernel/rh_taint.c and setup_arch references, then reproduce the boot failure on the Dell PowerEdge R730 with the Broadcom BCM57800 adapter. Compare the behavior across the reported LVS kernel versions and the CentOS 6.4 kernel; done means establishing whether the failure is an unsupported-hardware compatibility issue and documenting the supported path.
