我在内核 dmesg 中得到以下日志。我不知道为什么会这样。有时我的内核会不断重启，但并不总是这样。
<6>[ 0.233184] ram_console: got buffer at 42d80000, size 80000
<4>[ 0.233184] BUG: Your driver calls ioremap() on system memory. This leads
<4>[ 0.233215] <4>to architecturally unpredictable behaviour on ARMv6+, and ioremap()
<4>[ 0.233215] <4>will fail in the next kernel release. Please fix your driver.
