Hotplugging about MMC

	I have a MMC card with FAT filesystem.
	I copy a file to it(first open, then write).
	During writing, I pulled out MMC card and an uncomplete file have been 
	created on it.
	I open and read this uncomplete file later, printing error messages as 
below:

	FAT: Filesystem panic (dev mmcblk0p1)
	    fat_bmap_cluster: request beyond EOF (i_pos 3655251)
	    File system has been set read-only
	FAT: Filesystem panic (dev mmcblk0p1)
	    fat_bmap_cluster: request beyond EOF (i_pos 3655251)

Now I expect kernel don't create an uncomplete file when pulling out MMC 
card,
How can I do?

Regards,
Richard

Then you expect too much. Only journaling filesystems that also journal
data (like ext3) can handle something like that.

This is not the forum for a question like this anyway since this list is
about wbsd, not vfat. Please direct your question to
linux-kernel <at> vger.kernel.org.

A few points.

1. If I send you patches I expect you to report the results. How am I
supposed to know if they solve your problem and should be included in
future versions otherwise?

2. Use the mailing list for questions. Other people might be able to
answer your questions and it will be stored in the archive for future
people to see.

Hi!

1. If I don't load the modules, there is happening nothing.
2. If I load the modules, appear in dmesg the following :
wbsd: Winbond W83L51xD SD/MMC card interface driver, 1.3
wbsd: Copyright(c) Pierre Ossman
pnp: Device 00:01 activated.

If i remove it :

wbsd: Card removed

I see the problem. The kernel you're running doesn't have SD support.
You should install 2.6.14 or newer.

Compal CL56 / Zepto Znote 4200

I have this computer and I get the driver loaded (running ubuntu). When
I load it with irq 10 and dma / fifo I get it up in dmesg but it seems
not to see when I insert a card. 

Here is some info from /sys. The most disturbing is the disabled status,
but where do I enable?

stian <at> porty:/sys/bus/pnp/devices/00:0a$ ls
bus  id  options  power  resources
stian <at> porty:/sys/bus/pnp/devices/00:0a$ cat id
WEC0518
stian <at> porty:/sys/bus/pnp/devices/00:0a$ cat resources
state = disabled
stian <at> porty:/sys/bus/pnp/devices/00:0a$ cat options
Dependent: 01 - Priority acceptable
   port 0x248-0x248, align 0x7, size 0x8, 16-bit address decoding
   irq 6 High-Edge
Dependent: 02 - Priority acceptable
   port 0x200-0x2ff, align 0x7, size 0x8, 16-bit address decoding
   irq 6,10,11 High-Edge
stian <at> porty:/sys/bus/pnp/devices/00:0a$

Hope you have some tips!

More console output:
dmesg:
[4381954.752000] wbsd: Winbond W83L51xD SD/MMC card interface driver,

The problem is that you've loaded wbsd without pnp support. What flags
are you giving the module?

I am using an SD card. The reader is internal so how they have set it up I dont know, but it is said to read both SD
