If so, can you try the workaround in bug 466607 comment #24? This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Updating this bug with latest rawhide tests. I'm still unable to boot rawhide from my external USB disk. All the 2.6.29 rcs have the same problem. I still have a 2.6.27 installed which boots just fine. The kernel boots fine, but things go bad after the handoff to the initrd init script. The bug still appears to be either a race condition, or an insufficient delay waiting for the USB device to settle. In the failed boot case, you can see kernel messages on the console about [sda] being discovered, but nonetheless it fails to mount the root fs shortly after. If I add a "sleep 10" command before "modprobe wait_scsi_scan", it does boot and everything is okay. Looking at the initrd init scripts between the 2.6.27 and 29, they're almost identical except 2.6.27 doesn't modprobe and rmmod scsi_wait_scan... I boot the kernels with 'nomodeset'. How can I provide better debug information ? Just wanted to add, after reading the bug mentioned in #1, that the USB disk does NOT use LVM. It has 2 partitions, the boot partition being the 2nd one :
> sudo fdisk -l /dev/sdb
Disk /dev/sdb: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00029d04
Device Boot Start End Blocks Id System
/dev/sdb1 1 47084 378202198+ 83 Linux
/dev/sdb2 * 47085 48641 12506602+ 83 Linux
Denis, can you please publish the init script from your .27 initrd?
I'm getting just the same behavior with vmlinuz-2.6.27.15-170.2.24.fc10.x86_64
from Fedora update repo, and the same hack with sleep 10 works for me.
But you said that:
>I still have a 2.6.27 installed which boots just fine
Actually, I can no longer reproduce this problem as of 2.6.29-0.215.rc7 Kiril, does that kernel work for you ? Yes, it works. But my problem is i can't use 29 kernel, I'm forced to use 27 kernel due to OpenAFS which is only avail as rpm for Fed10 official 27 kernels. Ok. Closing, since this appears resolved for F-11... |
