SquashFS Errors

Problem Statement

Some users have reported being unable to boot from the Ubuntu LiveCD, due to SquasFS errors like this:

SQUASHFS error: sb_bread failed reading block 0x9d7f3
SQUASHFS error: Unable to read fragment cache block [275faa28]
SQUASHFS error: Unable to read page, block 275faa28, size 23a7

Causes and Solutions

These errors can be due to a variety of reasons:

• bad memory modules (solution: use memtest86+ to check your memory)
• a bad dvd drive (solution: if possible, try using a different cd/dvd drive)
• bad data cable (solution: change it for a new one)
• bad media (solution: try burning the iso image to a new disc)
• a corrupted iso image (solution: run an md5 checksum, and if they don't match, download the iso image again)

Temporary Workarounds

Some users have reported that adding the ide=nodma or acpi=off allowed them to work around this issue (which proved to be bad memory modules). You might want to give that a try Successful boot was achieved by adding "all_generic_ide" to the grub boot line for the live CD.
