Hi Tony and folks, Recently, Felipe sent some patches that finish converting isp1301_omap.c to new-style i2c driver. Such patches were already pushed into Linux-OMAP tree [1]. Well, regarding arch/arm/mach-omap1/board-h2.c file, he proposed to add i2c_register_board_info() call at h2_init_irq(void). Unfortunately, this call causes kernel panic when booting TI H2 boards. Find below the debug message: ... Backtrace: [<c0088c28>] (kmem_cache_alloc+0x0/0x84) from [<c001ca84>] (i2c_register_board_info+0x54/0xd8) r7:00000001 r6:00000001 r5:c00255fc r4:c00255c8 [<c001ca30>] (i2c_register_board_info+0x0/0xd8) from [<c0011d04>] (h2_init_irq+0x28/0x4c) r8:10022bc4 r7:c02bdc9c r6:c0024f1c r5:c02db110 r4:c02db104 [<c0011cdc>] (h2_init_irq+0x0/0x4c) from [<c000ef58>] (init_IRQ+0x38/0x48) [<c000ef20>] (init_IRQ+0x0/0x48) from [<c0008c8c>] (start_kernel+0x16c/0x2d8) [<c0008b20>] (start_kernel+0x0/0x2d8) from [<10008034>] (0x10008034) r6:c0025320 r5:c02dba08 r4:00053175 Code: e1a07001 e10f4000 e3843080 e121f003 (e5902000) <0>Kernel panic - not syncing: Attempted to kill the idle task! ... So, I'm proposing this patch that adds i2c_register_board_info() call at h2_init(void), as it's done on H3 board file, in order to fix the kernel panic mentioned above. Testing, booting and working fine. BR, Carlos.
