Mention that the error string is: "lpro aio ramdisk device not registered exclusive" and that you have ruled out brd loading issues and lock contention.
Many proprietary drivers read a module parameter like ramdisk_major or aio_ring_size. If these parameters point to a non-existent major/minor device number (e.g., ramdisk_major=254 but no device with that major exists), the driver cannot register.
while [ ! -e /dev/ram0 ]; do sleep 0.1 done modprobe lpro
Then run: update-initramfs -u
The error “lpro aio ramdisk device not registered exclusive” is a resource conflict at the kernel level. It indicates that the driver’s request for exclusive access to a device number or memory region was denied. The issue can be temporarily resolved by removing conflicting modules, but a long-term solution requires driver modification to avoid unnecessary exclusive registration or to handle conflicts gracefully.
Severity: Medium (blocks application functionality but system otherwise stable)
Status: Awaiting driver patch or configuration change
Attachments: (dmesg excerpt, module source snippet if available)
