##Problem description Sometime after a **reboot** command the FOX Board G20 hangs. ##Solution If you are using a self compiled kernel 2.6.38 uImage comment these two lines on **arch/arm/mach-at91/at91sam9_alt_reset.S**: and make again a uImage:

//str   r2, [r0, #AT91_SDRAMC_TR]       @ disable SDRAM access
//str   r3, [r0, #AT91_SDRAMC_LPR]      @ power down SDRAM

If you are using an Acme factory default uImage download this uImage file: * [uImage_reboot](http://terzo.acmesystems.it/download/microsd/uImage_reboot) (MD5: 0f2ea8f58cb35bef889058077751a27f) Rename it in **uImage** and copy it on the first microSD FAT32 partition called "kernel". You can change it remotely copying the uImage in the directory **/media/mmc_p1**:

$ scp uImage_reboot root@[fox IP number]:/media/mmc_p1/uImage

and rebooting the FOX.
