Created attachment 324989 [details] Dmesg from system booted with disc in the drive Description of problem: When booting the F10 release kernel the kernel will freeze when trying to initalise the DVD drive if there isn't a disc present in the drive. Version-Release number of selected component (if applicable): kernel-2.6.27.5-117.fc10.x86_64 How reproducible: Always Steps to Reproduce: 1. Install F10 2. Remove install disc from drive 3. Reboot Actual results: Kernel freezes during SCSI initialisation Expected results: Boot proceeds. Additional info: The last messages before the freeze are: scsi 2:2:1:0: Direct-Access DELL PERC 6/i 1.11 PQ: 0 ANSI: 5 scsi 2:0:32:0: Attached scsi generic sg1 type 13 sd 2:2:0:0: [sda] 155189248 512-byte hardware sectors (79457 MB) sd 2:2:0:0: [sda] Write Protect is off sd 2:2:0:0: [sda] Mode Sense: 1f 00 00 08 sd 2:2:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 2:2:0:0: [sda] 155189248 512-byte hardware sectors (79457 MB) sd 2:2:0:0: [sda] Write Protect is off sd 2:2:0:0: [sda] Mode Sense: 1f 00 00 08 sd 2:2:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sda3 sda4 < sda5 sda6 sda7 sda8 > sd 2:2:0:0: [sda] Attached SCSI disk sd 2:2:0:0: Attached scsi generic sg2 type 0 sd 2:2:1:0: [sdb] 2927099904 512-byte hardware sectors (1498675 MB) sd 2:2:1:0: [sdb] Write Protect is off sd 2:2:1:0: [sdb] Mode Sense: 1f 00 00 08 sd 2:2:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 2:2:1:0: [sdb] 2927099904 512-byte hardware sectors (1498675 MB) sd 2:2:1:0: [sdb] Write Protect is off sd 2:2:1:0: [sdb] Mode Sense: 1f 00 00 08 sd 2:2:1:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdb1 sd 2:2:1:0: [sdb] Attached SCSI disk sd 2:2:1:0: Attached scsi generic sg3 type 0 ...when booting from the rescue CD the line which immediately follows is: scsi3 : ioc0: LSI53C1020A A1, FwRev=01032700h, Ports=1, MaxQ=255, IRQ=16 which relates to: sr0: scsi3-mmc drive: 24x/24x cd/rw xa/form2 cdda tray I'll attach a full dmesg from the system booted with a disc in the drive, but the order of messages appears to be different here to when it fails (the scsi3 messages appear later). I should also add that when the kernel freezes inserting a disc will not cause it to continue. You have to start the boot with a disc in the drive.

I think the underlying cause is similar to #466607. I've created the file /etc/sysconfig/mkinitrd and put in the line: MODULES="scsi_wait_scan" ..and recreated the initrd and the machine now boots without a disc in the drive. It seems therefore that the SCSI module isn't waiting long enough for the drive to initialise, and putting a disc in it allowed it to initialise slightly faster and boot. Several other people seem to be reporting similar problems on the mailing list so I suspect that this is something which may affect a few different SCSI controllers.

This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
