Display Unchecked space...

Display Unchecked space...

[Steve Tsai]

Hi,

I download the latest cvs code and build it in uClinux. After running
two days, I got "kernel BUG at gc.c:136! Checked all inodes but still
0x6a0 bytes of unchecked space?" and it will continue display the
message and halt the system. I set CONFIG_JFFS2_FS_DEBUG=1, but I did
not get any useful messages. Does anyone can tell me why the kernel BUG
will display? Could I solve the system halt, even "unchecked space"
occurs? Thanks.

Hi Steve 

I got the same yesterday. I am using the preempt patch and the cfi_cmdset0001.c
driver. I guessing it's a locking problem, but now I not that sure anymore, I
don't think uClinux can do preempt? What's your CVS version of jffs2/write.c 
and cfi_cmdset0001.c(if you use that driver)?

Can you repeat it?

You also need to edit kernel/printk.c and set DEFAULT_CONSOLE_LOGLEVEL to 
9, to ensure that the KERN_DEBUG messages are actually printed to the 
console.

Then log all the messages, compress them and send them to me.

I meant jffs2/nodelist.c, not jffs2/write.c.

We think this is fixed. cvs up and try again.
