linux-image-6.12.27-amd64: CONFIG_SATA_MOBILE_LPM_POLICY=3 caused system freezing several seconds with ata ncq/dma errors

[Mehmet ÇELEN <celenmeh@gmail.com>]

Dear Maintainer,

I am reporting an issue with the default config of CONFIG_SATA_MOBILE_LPM_POLICY=3. I'm not sure if it's considered as a bug but it caused serious issues with my system communicating with the SSD device - causing freezings for several seconds every random time. Maybe I should report this to the SSD firmware or kernel; but this issue did not occur on Debian 12 with the same SSD device where CONFIG_SATA_MOBILE_LPM_POLICY=0. The change was done last year: https://github.com/torvalds/linux/blame/ec7714e4947909190ffb3041a03311a975350fe0/drivers/ata/Kconfig#L121


What led up to the situation?
- Attached errors caused system freezing for several seconds and hard resetting
communication between the kernel and SSD device every random time.

What exactly did you do (or not do) that was effective (or ineffective)?
- 1. Replaced the SATA data/power cables to new ones was ineffective.
  2. Changed the ata port from 10 to 9. Ineffective
  3. Turn off NCQ. Ineffective, I started to see DMA errors with the same pattern.
  4. Setting boot parameter (via grub config) ahci.mobile_lpm_policy=1,
effective no issues/errors for 2 days. I see this config by default has
value 3 as in kernel source.
