Thanks - one other thing that's needed is to prevent the build from failing when it finds this module was in the previous build but not the current. I'm not sure the right way to do that - I just removed it from the list of modules in the previous build. Other than that - builds and boots fine - and system clock gets set properly as you can see in the dmesg output below: Booting Linux on physical CPU 0 Initializing cgroup subsys cpuset Initializing cgroup subsys cpu Linux version 3.5.0-9-highbank (ubuntu@ubuntu) (gcc version 4.7.1 (Ubuntu/Linaro 4.7.1-6ubuntu1) ) #9 SMP PREEMPT Fri Aug 10 18:37:26 CDT 2012 (Ubuntu 3.5.0-9.9-highbank 3.5.0) CPU: ARMv7 Processor [413fc090] revision 0 (ARMv7), cr=10c5387d CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache Machine: Highbank, model: Calxeda Highbank cma: CMA: reserved 16 MiB at 2e800000 Memory policy: ECC disabled, Data cache writealloc On node 0 totalpages: 1046784 free_area_init_node: node 0, pgdat c05fdd80, node_mem_map c1428000 Normal zone: 1710 pages used for memmap Normal zone: 0 pages reserved Normal zone: 192850 pages, LIFO batch:31 HighMem zone: 7491 pages used for memmap HighMem zone: 844733 pages, LIFO batch:31 PERCPU: Embedded 7 pages/cpu @c3838000 s6720 r8192 d13760 u32768 pcpu-alloc: s6720 r8192 d13760 u32768 alloc=8*4096 pcpu-alloc: [0] 0 [0] 1 [0] 2 [0] 3 Built 1 zonelists in Zone order, mobility grouping on.

rtc-pl031 is the driver used for the RTC on the highbank platform. We build it as a module in precise/quantal, but that makes it unavailable in early boot, which results in this error message: /build/buildd/linux-3.2.0/drivers/rtc/hctosys.c: unable to open rtc device (rtc0) And also prevents us from being able to accurately check the last-mounted time on the root filesystem.
