Public bug reported:
When resuming from suspend by opening the laptop lid, the following
errors appear repeatedly:
- "Failed to write b = 0: -6"
- "PM: failed to resume async: error -6"
- "PM: dpm_run_callback(): spd5118_resume [spd5118]"
- "returns -6"
The errors are related to the SPD5118 DDR5 temperature sensors. dmesg shows
four sensors:
- spd5118 1-0050: DDR5 temperature sensor: vendor 0x06:0x32 revision 1.6
- spd5118 1-0051: DDR5 temperature sensor: vendor 0x00:0xb3 revision 2.2
- spd5118 1-0052: DDR5 temperature sensor: vendor 0x06:0x32 revision 1.6
- spd5118 1-0053: DDR5 temperature sensor: vendor 0x00:0xb3 revision 2.2
The errors appear consistently on resume but do not seem to affect
system stability or memory functionality.
System Information:
- Ubuntu 25.04 (Noble Numbat) Preview
- ThinkPad [your specific model number]
- Kernel version: [output of uname -r]
Steps to reproduce:
1. Close laptop lid (system suspends)
2. Open laptop lid (system resumes)
3. Observe spd5118 errors in logs
Note: i have observed this same error in Ubuntu 24.04 and 24.10 also.
