"S3C2410 PM Suspend Memory CRC" feature (controlled by SAMSUNG_PM_CHECK config option) is incompatible with highmem (uses phys_to_virt() instead of proper mapping) which is used by the majority of Exynos boards. The issue manifests itself in OOPS on affected boards, i.e. on Odroid-U3 I got the following one: Unable to handle kernel paging request at virtual address f0000000 pgd = 1c0f9bb4 [f0000000] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM [<c0458034>] (crc32_le) from [<c0121f8c>] (s3c_pm_makecheck+0x34/0x54) [<c0121f8c>] (s3c_pm_makecheck) from [<c0121efc>] (s3c_pm_run_res+0x74/0x8c) [<c0121efc>] (s3c_pm_run_res) from [<c0121ecc>] (s3c_pm_run_res+0x44/0x8c) [<c0121ecc>] (s3c_pm_run_res) from [<c01210b8>] (exynos_suspend_enter+0x64/0x148) [<c01210b8>] (exynos_suspend_enter) from [<c018893c>] (suspend_devices_and_enter+0x9ec/0xe74) [<c018893c>] (suspend_devices_and_enter) from [<c0189534>] (pm_suspend+0x770/0xc04) [<c0189534>] (pm_suspend) from [<c0186ce8>] (state_store+0x6c/0xcc) [<c0186ce8>] (state_store) from [<c09db434>] (kobj_attr_store+0x14/0x20) [<c09db434>] (kobj_attr_store) from [<c02fa63c>] (sysfs_kf_write+0x4c/0x50) [<c02fa63c>] (sysfs_kf_write) from [<c02f97a4>] (kernfs_fop_write+0xfc/0x1e4) [<c02f97a4>] (kernfs_fop_write) from [<c027b198>] (__vfs_write+0x2c/0x140) [<c027b198>] (__vfs_write) from [<c027b418>] (vfs_write+0xa4/0x160) [<c027b418>] (vfs_write) from [<c027b5d8>] (ksys_write+0x40/0x8c) [<c027b5d8>] (ksys_write) from [<c0101000>] (ret_fast_syscall+0x0/0x28) Add PLAT_S3C24XX, ARCH_S3C64XX and ARCH_S5PV210 dependencies to SAMSUNG_PM_CHECK config option to hide it on Exynos platforms.
