进入dracut前的屏幕输出

Description of problem:
在从4.19.91-24.8.an8 内核升级到5.10.134-14.an8 （龙蜥8仓库中对应rpm包）的时候，发现一些服务器，升级前硬盘对应SAS卡的驱动是isci，但是升级后系统盘无法启动，找不到对应LVM分区，我看新内下没有isci的驱动模块文件，请问如何解决。
对应SAS卡在4内核下的pci信息如下：
lspci -nn|grep -i sas
03:00.0 Serial Attached SCSI controller [0107]: Intel Corporation C606 chipset Dual 4-Port SATA/SAS Storage Control Unit [8086:1d68] (rev 06)

问题原因是在5.10的config文件中CONFIG_SCSI_ISCI没打开，导致isci.ko驱动没有。

Comment 4 gumi alibaba_cloud_group 2023-11-10 16:53:14 UTC 
问题已分析清楚，是anck-5.10 config关闭了iscsi驱动配置，导致isci驱动没有编译。修改方案为将isci驱动配置为m，开启编译。解决此问题。
