The ISO file integrity check was recently changed so it now runs in the background. It does not show while booting or delay boot.

Cases where the crash can be triggered: - Using a Virtualbox VM, where graphics acceleration is handled by mesa with LLVMPIPE - Start the ISO on real hardware in 'safe graphics mode' Cases where the crash is not encountered: - Start the ISO on real intel (HD graphics) hardware with full acceleration. NOTE: The crash can be avoided by downgrading MESA 21.0.x packages to the previous 20.3.4 in hirsute. Try/Install crash: Screen fails to start, or starts then crashes on any user action. The user is presented with: "Installation failed - The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again" Live session crash: The installer does not start from the desktop icon. Starting ubiquity from the terminal results in an "Aborted (core dumped)" message and nothing else. The crash is most commonly "malloc(): unaligned tcache chunk detected", but inevitably from this sort of memory issue can be something like "realloc(): invalid next size" An example /var/log/installer/debug log from a session where both crashes were triggered is below. **** /var/log/installer/debug **** Ubiquity 21.04.11 TEXT <small>If more than one person will use this computer, you can set up multiple accounts after installation.</small> TEXT <small>Enter the same password twice, so that it can be checked for typing errors.</small> TEXT <small>The name it uses when it talks to other computers.</small> TEXT <small>Enter the same password twice, so that it can be checked for typing errors.</small> TEXT <small>Enter the same password twice, so that it can be checked for typing errors.</small> TEXT <small>If more than one person will use this computer, you can set up multiple accounts after installation.</small> TEXT <small>Enter the same password twice, so that it can be checked for typing errors.</small> TEXT <small>The name it uses when it talks to other computers.</small> QSocketNotifier: Invalid socket 17 and type 'Read', disabling...
