ASA 9.1(7)31 not booting

[fhk-cseifert]

Hello community,

I upgraded an ASA 5540 from 9.1(7)23 to latest 9.1(7)31.

Sadly at the first boot of .31 interim, the asa not booting up and hung.

After changing boot image back to .23 at ROMMON, the ASA booting up fine.

Did someone have this issue too? I am running latest ADSM 7.9.2.152 too.

Thanks in advance for any hints and help.

Greetings, Chris

Looking through the 9.1(7) release notes, I see there was a bug in the 9.1(7)23 release with similar symptoms:

Upgrade of ASA5500 series firewalls results in boot loop (not able to get past ROMMON)

Could you try to run the workaround given in the bug notes and try again? If it fails, I would suggest contacting Cisco TAC for assistance.

Thank you very much. After the workaround of bug CSCvh91399 the build 31 is running fine. Two other ASAs are not running into this bug. All of them was at same release 9.1(7)23 before updating.

Did someone find the updated release notes of 9.1(7)31...? Build 29 are the last entry at the release notes:
