[Bug 243464] [NEW] [intrepid] initrd sometimes falls to busybox prompt

[Christian Roessner]

Public bug reported:

Binary package hint: initramfs-tools

Hi,

I am testing intrepid to help finding bugs :-)

When I start booting my system, I need 5-6 times to get my machine
booting. Often it falls back to the busybox prompt.

When I use that prompt and change into /dev/vg01 directory, only the
lv_p2 partition is seen there. So the lvm stuff does not find all
partitions.

My system is configured that way:

mount
/dev/mapper/vg01-lv_root on / type ext3 (rw,noatime,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
/proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
varrun on /var/run type tmpfs (rw,nosuid,mode=0755)
varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
/dev/md0 on /boot type ext3 (rw,noatime,errors=remount-ro)
/dev/mapper/vg01-lv_p1 on /home type ext3 (rw,noatime,errors=remount-ro,data=writeback)
/dev/sdb1 on /media/windows type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,blksize=4096)
none on /proc/bus/usb type usbfs (rw,devgid=46,devmode=664)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
gvfs-fuse-daemon on /home/croessner/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=croessner)

Busybox is telling me that it can not find the given UUID. Combined with
the missing lvm stuff, it is saying the truth :-)

So it might be some timeing problems with scanning LVM
