Hi!
After upgrading to latest 15.4 OSX I get system crashes when reopening a lid.
panic(cpu 2 caller 0xfffffe0046c0aef8):
AOP DATA ABORT
pc=0x0000000001091a00
Exception class=0x25 (Data Abort taken without a change in Exception level)
IL=1, iss=0x6
far=0x0000000000000005
Wrong frame size for ARMv8. Got 840 bytes, expected 828.
Is there anyway to downgrade OSX to previous version without reinstalling?
MacBook Pro 16″, macOS 15.4
Same issue. Everything was fine with 15.4 until I started using high impedance headphones (Sennheiser HD600\300 ohms). After talking to a senior tech at Apple, it seems the sensor that adjusts the output voltage to the headphones may be causing the issue when the Macbook is asleep while the headphones are still connected. This only happened to my machine when those headphones (never had an issue with low impedance headphones) were left plugged in and I closed the lid for around 15 minutes or more. When opening the lid in this scenario, I had to enter my password again and the kernel panic warning showed on my desktop. After removing the headphones BEFORE closing the laptop, the kernel panics ceased. I tested this multiple times. If enough people using high end headphones are having this issue, please test for yourselves and report it to Apple so they can fix this issue.

No.
Knowing the reason for the kernel panic doesn't really help anyone other than Apple, assuming they take an interest in it (more about that later). If it's some third party product incompatibility they will not be interested.
Review If your Mac restarts and a message appears - Apple Support. If you are sufficiently motivated to do so, contact the headphone's manufacturer, who is likely to tell you it's not their problem and to contact Apple. Apple in turn will probably tell you it's not their problem and to contact the headphone manufacturer.
In the unlikely event Apple identifies a fault with the Mac or with macOS, and Apple takes an active interest, then it will be up to them to fix it. They will not acknowledge a problem, but if there is one, it will be silently addressed in a future macOS update or upgrade. That can take anywhere from a few weeks to months, or more, but it's not as though they are just being obstinate or ignoring you.
But we can't easily "undo" macOS upgrades any more.
You may be able to advance troubleshooting if you were to start your Mac in "Safe Mode" Start up your Mac in safe mode - Apple Support and determining if the crashes manifest while in that mode, but not knowing what kind of headphones you have they may not even work in that mode. In any event it would be valuable information.
This thing is really annoying. According to ChatGPT log analysis the problem is in:
RTKit: RTKit-2784.100.168.release
Client: AppleSPUFirmwareBuilder-642.100.42~6072
The RTKit is involved, which is typically how macOS interacts with Apple Silicon's real-time coprocessors (like audio DSPs or security chips). The presence of AppleSPUFirmwareBuilder suggests this may be tied to secure firmware communication—perhaps for audio or a secure enclave.
It sounds kind of correct analysis, because just few minutes ago computer crashed righ after inserting headphones in. Sometimes it crashes when I open a lid and the computer wakes up from sleep...
Did anyone else had this problem after upgrading to 15.4?
How to proceed?
it looks like this issue frequently happens after upgrading to 15.4. And there is the same ticket created here
macOS 15.4 causes nightly kernel panic (W… - Apple Community
The same kernel panic after 15.4 upgrade! Hopefully apple fixes this issue in next update.
yeah, all my cases are that my macOS crashes during sleep.
Same. But not always.
