Public bug reported:
My Lenovo ThinkPad experiences thermal shutdowns immediately after
booting into Ubuntu kernel 6.8.0-60-generic, even when thermal
protection is explicitly disabled with `thermal.nocrt=1`. It works on
6.8.0-51-generic so I am using that as a work around and sending from
there.
**Steps to Reproduce:**
1. Boot into Ubuntu kernel 6.8.0-60-generic
2. Pass `thermal.nocrt=1` in GRUB_CMDLINE_LINUX_DEFAULT
3. Observe system logs and shutdown behavior
**Expected:**
- System should boot normally and ignore critical temperature shutdown due to
`thermal.nocrt=1`
**Actual:**
- System logs show:
thermal thermal_zone0: acpitz: critical temperature reached
reboot: HARDWARE PROTECTION shutdown (Temperature too high)
It booted once and when I checked temps all was good, but I couldn't get
it to do it again.
** Affects: linux (Ubuntu)
Importance: Undecided
Status: New
** Attachment added: "Version: Ubuntu 6.8.0-51.52-generic 6.8.12"
