 Additional debug information:
 
 System boot time: Sat Aug 16 09:17:26 2014
 First ld error: 2014-08-17T05:25:02
 Run time until crash: ~20h08m
 
 The pattern (sdmmcdebug=5) is:
 
 ld0: I/O operation (dir=IN, blkno=0x1404e0, bcnt=0x2000)
 sdmmc_mmc_command: cmd=18, arg=0x1404e0, flags=0x572
 sdmmc0: cmd 18 arg=0x1404e0 data=0xdb70c000 dlen=8192 flags=0x573 (error 60)
 sdmmc_mmc_command: error=60
 ld0: error 60
 ld0a: error reading fsbn 926944 of 926944-926959 (ld0 bn 1311968; cn 640 
 tn 39 sn 0)
 
 Seems to be MMC_READ_BLOCK_MULTIPLE erroring out with ETIMEDOUT pretty 
 quickly.
 Timeout in sdhc_exec_command() is hz or 10*hz (1 or 10 sec) but the 
 failure rate is significantly higher.
