#1993 closed defect (wontfix)

RAMDISK block size causes kernel panic

Reported by: nitoy08 Owned by: mchua pbrobinson sdz
Priority: Normal Milestone:
Component: Sugar on a Stick (SoaS) Version: SoaS 3 (Mirabelle)
Severity: Minor Keywords:
Cc: Distribution/OS: Fedora
Bug Status: Unconfirmed


Created LiveUSB on 8G card in USB adapter. Created soas-2-bluberry bootable system on this. With BIOS set for USB boot priority turned on machine (ACER 5315-2122). White "sugar on a stick" splash screen comes up. Then error (VERBATIM):

RAMDISK: incomplete write (3684 != 32768)
write error
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0, 0)

I can't add a bootparam to boot.conf for ramdisk_size because it is a read-only fs

  • Distribution/OS changed from Unspecified to Fedora
  • Milestone changed from Unspecified by Release Team to Mirabelle
  • Priority changed from Unspecified by Maintainer to Normal
  • Severity changed from Unspecified to Minor
  • Version changed from Unspecified to SoaS 2 (Blueberry)

This looks like an incomplete write of the liveusb-creator - could you retry this and report back? Also, comparing checksums of the .iso images might be helpful. Please feel free let me know if I can help with that! Trying out the newly released Mirabelle would also be an interesting thing to do.

  • Version changed from SoaS 2 (Blueberry) to SoaS 3 (Mirabelle)

After a *day* of trying more than half a dozen Live USB creators (mad props to the people at, that was the only one to work), I tried booting from soas-3-mirabelle. Got the splash screen, and the little grey circles got to about 9 O'clock around the X-O symbol in the middle, when the screen went blank and got the message: "No root device found, boot failed, sleeping forever". ARGGGH!
