The kernel would not boot on the hammerhead hardware due to the following error: mmc0: Timeout waiting for hardware interrupt. mmc0: sdhci: ============ SDHCI REGISTER DUMP =========== mmc0: sdhci: Sys addr: 0x00000200 | Version: 0x00003802 mmc0: sdhci: Blk size: 0x00000200 | Blk cnt: 0x00000200 mmc0: sdhci: Argument: 0x00000000 | Trn mode: 0x00000023 mmc0: sdhci: Present: 0x03e80000 | Host ctl: 0x00000034 mmc0: sdhci: Power: 0x00000001 | Blk gap: 0x00000000 mmc0: sdhci: Wake-up: 0x00000000 | Clock: 0x00000007 mmc0: sdhci: Timeout: 0x0000000e | Int stat: 0x00000000 mmc0: sdhci: Int enab: 0x02ff900b | Sig enab: 0x02ff100b mmc0: sdhci: AC12 err: 0x00000000 | Slot int: 0x00000000 mmc0: sdhci: Caps: 0x642dc8b2 | Caps_1: 0x00008007 mmc0: sdhci: Cmd: 0x00000c1b | Max curr: 0x00000000 mmc0: sdhci: Resp[0]: 0x00000c00 | Resp[1]: 0x00000000 mmc0: sdhci: Resp[2]: 0x00000000 | Resp[3]: 0x00000000 mmc0: sdhci: Host ctl2: 0x00000008 mmc0: sdhci: ADMA Err: 0x00000000 | ADMA Ptr: 0x70040220 mmc0: sdhci: ============================================ mmc0: Card stuck in wrong state! mmcblk0 card_busy_detect status: 0xe00 mmc0: cache flush error -110 mmc0: Reset 0x1 never completed. This patch increases the load on l20 to 0.2 amps for the sdhci and allows the device to boot normally.
