[Bug 2147408] Re: Ubuntu 26.04 Boots Into Emergency Mode When Using Multipath on ThinkSystem 440‑16e SAS/SATA PCIe Gen4 12Gb HBA.
Based on our latest test results, the boot issue is no longer reproducible on the 2026-04-24 build of Ubuntu 26.04. Given that the latest image has restored the expected behavior, I think we can close this defect.

[Bug 2147408] Re: Ubuntu 26.04 Boots Into Emergency Mode When Using Multipath on ThinkSystem 440‑16e SAS/SATA PCIe Gen4 12Gb HBA.
Hi Jeff, Here are my latest date: 3)Does this work with 24.04 and 25.10? We have tested this issue with 24.04 and the system boots successfully without entering emergency mode. 4)And when you say "Append the "rd.auto"," what do you mean? HOW are you appending it to allow this to work? Can you show a diff of the stock vs updated rd.auto? The issue no longer persists starting from the Ubuntu 26.04 (2026-04-24 build). I am not certain which specific updates between the 2026-03-08 and 2026-04-24 builds resolved it, but the fix appears to be included in the latest image. I have attached the logs for both the Ubuntu 26.04 (0424 build) and 24.04 for your reference.

Hi Jeff, Here are my response: 1)When you say "Install" what way are you installing this? Does the installation complete and it fails on first boot, or does the installer fail and it can't even get that far? The installation completes and it fails on first boot. 2)You're also doing, apparently, multipath on an external eSATA/eSAS device? We installed Ubuntu 26.04 on one of mutipath devices. 3)Does this work with 24.04 and 25.10? I have requested our tester to verify if the symptom persists. I will update the results here once available. 4)And when you say "Append the "rd.auto"," what do you mean? HOW are you appending it to allow this to work? Can you show a diff of the stock vs updated rd.auto? 4.1) We appended "rd.auto" to the Ubuntu 26.04 installer boot parameters. After completing the installation, the OS can boot successfully. 4.2) Currently, the tester has only provided a screenshot without "rd.auto". I have requested the tester to re-run the test with the latest Ubuntu 26.04 build to check if the symptom persists. If it does, I will provide the rdsosreport.txt here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2147408 Title: Ubuntu 26.04 Boots Into Emergency Mode When Using Multipath on ThinkSystem 440‑16e SAS/SATA PCIe Gen4 12Gb HBA.
