Description Pablo Iranzo Gómez 2009-09-21 07:00:16 UTC

Description of problem:
On aparently random reboots, Fedora kernel changes IDE HDD from 'sdb' (imho it should be hda), to 'sda', causing problems in boot

Version-Release number of selected component (if applicable):

Fedora rawhide updated until yesterday

How reproducible:


Steps to Reproduce:
1. boot computer
2. have fsck abort while trying to check 'sda1' (supposedly /boot)
3. check that 'sda' is not SATA drive 1, being instead IDE drive 1 renamed.
4. reboot
5. sometimes it will work
  
Actual results:

-IDE hdd is using ide-scsi
-Drive ordering is changing randomly


Expected results:
-IDE drives should be hd* as with previous releases
- most important: drive ordering should not change randomly


Additional info:
after putting LABEL="/boot" in fstab and using e2label to label correct drive, I always get my system booting, sometimes as 'sdb', sometimes as 'sda' (checked when asking for LUKS password)

The kernel is using the libata drivers, not ide-scsi. Drive order changing randomly is expected and the installer sets up fstab using labels and/or UUIDs to deal with that.
