当我启动服务器时，它显示以下内容并永远挂起：
[ 88.166038] usb 2-1: device not accepting address 2, error -110
[ 88.285980] usb 2-1: new high-speed USB device number 3 using ehci_hcd
[ 93.423935] dracut Warning: No root device "block:/dev/disk/by-uuid/3be3a552-7f1e-42dc-b59d-c220cf349cd6" found
[ 103.858270] usb 2-1: device not accepting address 3, error -110

[ 114.423040] usb 2-1: device not accepting address 4, error -110
从恢复磁盘中，我可以很好地看到该磁盘：
# blkid
/dev/sdm1: LABEL="/BOOT" UUID="7fd96db0-68b6-484f-96d4-bf65282160cd" TYPE="ext3"
/dev/sdm2: LABEL="/" UUID="3be3a552-7f1e-42dc-b59d-c220cf349cd6" TYPE="ext3"
# ls /dev/disk/by-uuid/3b*
/dev/disk/by-uuid/3be3a552-7f1e-42dc-b59d-c220cf349cd6
我的 grub.conf 看起来像这样：
timeout=5
default=0
title Linux (3.2.27-0.4.18.wd.0.31.231.metal1.x86_64)
root (hd0,0)
kernel /vmlinuz-3.2.27-0.4.18.wd.0.31.231.metal1.x86_64 ro root=UUID=3be3a552-7f1e-42dc-b59d-c220cf349cd6 nousb console=ttyS1,115200n8 earlyprintk=vga,keep
initrd /initramfs-3.2.27-0.4.18.wd.0.31.231.metal1.x86_64.img
我尝试通过添加 rdshell 和 rdinitdebug 内核参数来进入 dracut 调试 shell，但似乎没有任何反应。我可以通过其他方式进行调试吗？任何帮助表示赞赏！
