Dear group, before going into a thorough research I ask you if you ever experienced this: 8 out of 10 reboots of the BBxM stop due to kernel oops at totally random moments in the boot process. I have tested it on multiple BB and I get always Oops. At some times the boot sequence can get to the login without oops, but rarely.
Pasting here a few examples gathered from the console at boot (just the beginning of the oops message): [ 4.951324] udevd[85]: starting version 175 [ 5.144683] usb 2-2: new high-speed USB device number 2 using ehci-omap [ 5.222869] Unable to handle kernel paging request at virtual address 1edf8026 [ 5.230438] pgd = de3e4000 [ 5.233276] [1edf8026] *pgd=00000000 [ 5.236999] Internal error: Oops: 805 [#1] SMP ARM [ 5.242004] Modules linked in: [ 5.245208] CPU: 0 PID: 118 Comm: udevd Not tainted 3.15.1-armv7-x2 #1 etc...
