Missing /dev/sda etc when booting custom kernels
A few people including me have had udev-151 only sparsely populate /dev -- crucial block devices such as /dev/sda were missing.
If you hit this problem, read /usr/doc/udev-151/README
In particular ensure your kernel meets the requirements:
- Version 2.6.27 of the Linux kernel with sysfs, procfs, signalfd, inotify,
unix domain sockets, networking and hotplug enabled:
CONFIG_TMPFS_POSIX_ACL=y (user ACLs for device nodes)
CONFIG_BLK_DEV_BSG=y (SCSI devices)
- Udev will not work with the CONFIG_SYSFS_DEPRECATED* option.
- Unix domain sockets (CONFIG_UNIX) as a loadable kernel module may work,
but it is not supported.
You should find that once your kernel meets these requirements, udev-151 works.
i discovered it helps a lot also if you switch from the deprecated (since 2.6.33) ide layer for sata to the new one (in device configuration): a common situation when upgrading configs from older kernel versions and booting without an initrd.
edit: sorry, read better your post, thought you were speaking about current.
btw, thanx for the hint.
Solved my probleam!
thank you!! i updated my gentoo but udev got broken. solved my problem.
thanks, this solved my problem, I was running out of ideas!
Just want to say that this solved my problem, too, and I can now boot my custom 2.6.34. Thanks!
