[ Reason ]
This update fixes bug #1128108. The bug was apparently always present
(see the bug's 'forwarded' link), but was never reported in Debian.
Now we received multiple reports. The bug was already fixed upstream.
[ Impact ]
The kernel panics at startup reproducibly (but intermittently) on some
Apple Silicon laptops due to a race between enabling auto suspend of
the SD card reader and loading the sdhci_pci driver.
[ Tests ]
The fix has been in testing for one month, where one of the reporters
tested it successfully, and it was tested by another reporters in trixie,
again with success.
[ Risks ]
Virtually none. The fix just disables auto suspend of the SD card reader.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
The fix is to disable auto suspend for the specific model of SD card reader
present on Apple Silicon machines, only on these machines. Apparently, auto
suspend is not supported anyway. In practice, this update adds an udev hwdb
override file [1] to the package.
[ Other info ]
asahi-scripts is a required package on all Apple Silicon machines (installed
by the asahi-platform-core metapackage).

+Subject: Install hwdb file to override auto suspend on GL9755 SD card reader
+
+systemd v255 shipped a hwdb update enabling auto suspend (runtime PM)
+for the SD card reader Apple uses in 14- and 16-inch Macbook Pros and
+Mac Studios
+(https://github.com/systemd/systemd/commit/2f72e94984fc2994ab27
5e384f92e15cc026264).
+This PCI ID is imported from ChromiumOS. The driver in upstream Linux
+does not support runtime PM so this change is questionable to useless.
+Unfortunately it creates a race between enabling auto suspend and probing
+the sdhci_pci driver. If the default idle timeout (2000 ms) triggers
+before the driver is bound the default PCI device runtime suspend
+callback will be called. On Apple silicon devices the GL9755 card
+reader is inaccessible after it is resumed for the driver's probe
+function. Accessing the device's BAR results in a SError with
+ESR = 0x92000018.
+It's not entirely clear whether which is an issue with the device or
+with Apple silicon's PCIe implementation or Linux driver.
