I installed a linux OS into SD card, but sometimes it can recognise the SD card when the kernel initialization, sometime it cannot recognise the SD card, so the system can't normal work, I doubt that it is the USB IRQ problem, if someone encountered some problem with me? I need help about it.
The SD card slot bundle in PCMCIA.

You mean you installed a distro onto a PCMCIA SD card???

What distro? Where does it start complaining?

yes, I made a small linux OS, and installed it into my PCMCIA SD card.

I think that it is a usb problem.
below is the kernel init information:

usb 1-3: new high speed USB device using ehci_hcd and address 3
usb 1-3: can't set config #1, error -110

but sometimes it is no complain, and it can correct find my SD card.

but pcmcia code and usb code don't seem related enough to me...

Can you check the pcmcia code?

The sd card is bundle with pcmcia, it is no related with pcmcia, in bios, the sd card is used by usb in BIOS, so it only seem is a usb device when kernel init.

I will suggest that you try to repeat the same thing with the newest kernel (2.6.20 as of now I think). If the problem persists, I think it would warrant a kernel bug report.

Well, maybe. I get this "error":

usb 1-3: can't set config #1, error -110 about once out of every three times that I boot, yet all my USB devices work fine. (One other time out of three, I get an error about the device not accepting "address 1", but it still works. The third time out of three, I get no errors.)

I have therefore decided that it shows up because USB is a really really stupid bus design. (Hotplug is one thing, but not being able to tell when all the connected devices have announced their presence? Come on. :p)

dfengui -- I would suggest looking deeper for the problem, because I don't think that what you posted is it. Are there other errors? Are you getting some kind of kernel panic? What, EXACTLY, are you seeing that isn't working right?
