Title:
Suspend/resume broken on MacBook Air 11-inch with kernel 6.17.0-6
(regression from 6.17.0-5)

Status in linux package in Ubuntu:
New

Bug description:
System fails to resume from suspend on MacBook Air 11-inch
(MacBookAir5,1) with kernel 6.17.0-6-generic.

SYMPTOMS:
- Lid close triggers suspend correctly (enters S3 deep sleep)
- On lid open, system never wakes - completely unresponsive
- Requires hard power-off and cold boot to recover
- No resume logs - system is completely frozen

REGRESSION:
- Kernel 6.17.0-5-generic: suspend/resume works perfectly
- Kernel 6.17.0-6-generic: suspend/resume completely broken
- Same system, same configuration, only difference is kernel version

SYSTEM:
- Hardware: MacBook Air 11-inch Early 2012 (MacBookAir5,1)
- Ubuntu 25.10
- TLP installed for power management
- ACPI reports: supports S0 S3 S4 S5

LOGS:
Last successful suspend on 6.17.0-5:
- PM: suspend entry (deep) at 10:48:55
- ACPI: PM: Waking up from system sleep state S3 at 10:49:00
- Clean resume, no errors

Failed suspend on 6.17.0-6:
- PM: suspend entry (deep) at 23:25:06
- [no resume logs - system frozen]
- Required hard reset at 08:54:49 next day

WORKAROUND:
Pinned GRUB to boot 6.17.0-5-generic until fixed.
