OK. There have been some regressions in the scsi area but I thought that a) they were fixed and b) none manifested as an oops in slave_alloc().

Perhaps James can take a look please?

Well, this does illustrate one of the problems of making everything
static: slave_configure isn't a terribly distinguished name. However, I'd bet this is usbstorage/scsiglue.c:slave_configure()

the taxonomy looks identical to bugs 11088 and 11072. Which are being fixed (have been fixed) in the USB tree.

Hi Andrew,

with the new kernel 2.6.26.3 the SD are now read and wrote correctly, but SDHC are not read! The kernel repeat the error. Follow the error:

This is definitely a USB issue (correct cc's added). It looks like some attempted reset finally ...

... leads to disconnection here.

Sep  1 22:20:14 athos kernel: sd 5:0:0:0: Attached scsi generic sg3 type 0

This is all symptomatic of the command SCSI is trying to send never reaching the device.

Then USB begins again with the same device:

Quoted 4 lines
Sep  1 22:20:14 athos kernel: usb 1-6: new high speed USB device using ehci_hcd and address 6
Sep  1 22:20:14 athos kernel: usb 1-6: configuration #1 chosen from 1 choice

Sep  1 22:20:19 athos kernel: scsi 6:0:0:0: Direct-Access     Generic  USB SD Reader    1.00 PQ: 0 ANSI: 0

And runs into identical problems.

Most likely, knowing USB, it's either some interface problem, or the device hung up on a SCSI command it didn't like. What's the last known good kernel? If the usb people don't recognise it, then likely we'll need a bisection search from there.

Try building a kernel with CONFIG_USB_STORAGE_DEBUG enabled and post or attach the dmesg log showing what happens when you plug in the device.

Have you checked that the reader does in fact support SDHC? They tend to fail in all sorts of ways when they don't.
