Hi All I am using ARM based board. In mine, i did the following... void __iomem *tcpm_base = ioremap_nocache(0x03B00000, 10*SZ_3MB); Actually i didnt reserve the 30MB memory @ 0x3B00000. But still the call is succesful and i am able to read the memory. In the logs it is just showing a warning, to fix my driver as i am calling ioremap() on system memory. However if i try to write something on that memory, then only it is calling panic().. Don't you think it should throw panic()while calling the ioremap() itself. Because this sounds like a serious violation... What say? -- With regards, Sandeep Kumar Anantapalli,
