Public bug reported: [This is on Intrepid Alpha 4 kept upto date. Linux gallifrey 2.6.26-5-generic #1 SMP Fri Aug 15 13:54:58 UTC 2008]
The drives on this machine get assigned differently to /dev/sd* on each boot: This machine has: 2 PATA IDE discs (both IC35L060AVER07-0) a PATA DVD drive (DVD-ROM DVD-116) a PATA CD/RW drive (24MAXX 1040) a PATA zip drive (ZIP 100) on two controllers; an internal AMD 760 onboard: 00:07.1 IDE interface: Advanced Micro Devices [AMD] AMD-766 [ViperPlus] IDE (rev 01) and a Promise 20268 PCI card; sometimes the boot disc is sdb, sometimes it is sda If you grep the attached log for 'removable' you can see the zip drive flipflops between sda and sdb: Aug 24 00:36:33 gallifrey klogd: [ 5.036714] sd 0:0:1:0: [sda] Attached SCSI removable disk Aug 24 00:38:44 gallifrey klogd: [ 5.262494] sd 2:0:1:0: [sdb] Attached SCSI removable disk Aug 25 15:21:44 gallifrey klogd: [ 6.289556] sd 2:0:1:0: [sdb] Attached SCSI removable disk Aug 25 16:11:50 gallifrey klogd: [ 5.733587] sd 0:0:1:0: [sda] Attached SCSI removable disk (Neither case has had media in any of the removable devices). similarly grepping for sr[01] shows I think the cdrw and dvd swapping places. ls -l sd[abc]/device sr[01]/device lrwxrwxrwx 1 root root 0 2008-08-25 16:11 sda/device -> ../../devices/pci0000:00/0000:00:0c.0/host0/target0:0:1/0:0:1:0 lrwxrwxrwx 1 root root 0 2008-08-25 16:11 sdb/device -> ../../devices/pci0000:00/0000:00:0c.0/host1/target1:0:0/1:0:0:0 lrwxrwxrwx 1 root root 0 2008-08-25 16:11 sdc/device -> ../../devices/pci0000:00/0000:00:07.1/host2/target2:0:0/2:0:0:0 lrwxrwxrwx 1 root root 0 2008-08-25 16:11 sr0/device -> ../../devices/pci0000:00/0000:00:0c.0/host0/target0:0:0/0:0:0:0 lrwxrwxrwx 1 root root 0 2008-08-25 16:11 sr1/device -> ../../devices/pci0000:00/0000:00:07.1/host3/target3:0:0/3:0:0:0 In this case sdb and sdc are the hard discs. I suspect this isn't new in Intrepid; for a few verisons that machine had had boot problems pulling up RAID1 at boot; but it used to work a couple of versions ago (gutsy maybe). Fun fun. The board is a Tyan S2460.
