"IRQ LOCK : IRQ63 is locking the sytem, disable?" ?

A system for the basic stability of the arm, but then the Internet line, and sometimes there will be "IRQ LOCK : IRQ63 is locking the sytem, disable" Thus, the system appeared to die circle, constantly played this information, and why?
Please master guiding instructions. . . . . Thank you first

Re : "IRQ LOCK : IRQ63 is locking the sytem, disable"

Ethernet interruption after receiving it when problems arise, you may have to cut some of the core modules, I do not know what your specific system, but may use the same pins and the different functions of the complex.
See the following questions and answers.

"Hi,
"The PS/2 mouse is not working. If I send the data to
"The mouse
"It says
"Mouse timed out[1]
"Mouse timed out[1]

"But when I send data to the mouse, if I click it
"I am getting the following message

"IRQ LOCK : IRQ 68 is locking the system. Disabled.
"IRQ LOCK : IRQ 68 is locking the system. Disabled.
"And so on until I enter a break character.

Hmmm, this problem was fixed a while ago. . .

What are you using? version of the Kernel

Also, more importantly, I see that you 'Ampere using Assabet+Neponset
Here. If you want to use the PS/2 mouse support, you _must_ disable
CONFIG_SOUND_UDA1341 support due to SA-1111 multiplexed pin functions.
Refer to Intel SA-1111 ref GPIO documentation in the manuals and
Linux ARM list archives for additional background on Assabet+Neponset
PS/2 mouse support issues.

Did not find the reasons, I may not accurately describe the phenomenon, I use ftp or Telnet should be possible when there is the phenomenon, I use the kernel is 2.4.18+patch-2.4.18-rmk6+patch-2.4.18-rmk6-swl6

Re : "IRQ LOCK : IRQ63 is locking the sytem, disable"

So you use SMDK2410 or S3C2410 for developing, right? RMK had ever answered a similar question in linux-arm-kernel mailing list (though he only gave a hint about what may caused this). You could reference the following link :

Http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2003-March/014544.html

BTW, what do you use file system on NAND flash? I am using S3C2410 too. Maybe we could share the experience together. Thanks a lot.

Thank you, I was using the jffs2, my email is : zymcomes@sina.com
Very happy and you exchange
I have read, but I do not know what is IRQ63 interruption in the end? Laws should go?

Re : "IRQ LOCK : IRQ63 is locking the sytem, disable"

I solve the problem, Thank you, "Tell me what"

Re : "IRQ LOCK : IRQ63 is locking the sytem, disable"

Could you share the experient about how to solve this problem? Thanks a lot!

Kernel patch of Bug
In linux-2.4.18-rmk6-sw15

Find
#ifdef CONFIG_ARCH_S3C2410

Changed
#ifdef CONFIG_ARCH_S3C2410
