If you're comfortable with kexec'ing into an image in memory, then it's doable. If you've never done that before, then I'd make sure that you're able to get to the machine in case you mess up do you have a good reference for how I might do the kexec'ing into an image in memory part? I am trying to understand how that is different than the "unmount root without reboot" link above. Will kexecing into an image possibly give me the full effect of as if I had booted into a live thumbdrive? | 18:24:57 |

| Sahil | I don't know if this is the right place to ask but my nixos home server keeps shutting down and I cannot find a cause via systemctl | 19:54:56 |
 K900 | Is it an x86 server? | 19:55:09 |
| Sahil | yes | 19:55:19 |
| K900 | Do you have anything in /sys/fs/pstore? | 19:56:16 |
| Sahil | empty dir, let me know if theres anything that you might need | 19:58:04 |
| K900 | Check lsmod | grep pstore | 19:58:13 |
| Sahil changed their display name from Sahil Mishra to Sahil. | 19:58:18 |
| K900 | If it's showing anything, you should have pstore set up | 19:58:18 |
| K900 | So any logs possible will be, well, logged | 19:58:25 |
| K900 | Even after a kernel panic or something | 19:58:29 |
| K900 | So if you still have nothing, it's probably hardware | 19:58:36 |
| Sahil | efi_pstore 16384 0 | 19:58:42 |
| K900 | Then yeah, it's likely hardware | 19:58:54 |
| Sahil | that sucks thank you for the help | 19:59:03 |
| K900 | Maybe try monitoring the temperatures | 19:59:13 |
| Sahil | sure, will take a look next time i can boot it | 19:59:43 |
| K900 | Instantly powering down is what a lot of especially older x86 does when overheated | 19:59:48 |

| Sahil | * my open ssh printed this
Broadcast
The system will suspend now!
| 20:20:16 |
| Sahil | Redacted or Malformed Event | 20:20:33 |
| Sahil | I believe the issue was that the computer was suspending, i turned powerManagement off is that a bad idea | 20:34:50 |
