[SOLVED]no usb storage with kernel26-ck

rwd · 2010-11-07 23:15:31

I tried kernel26-ck 2.6.36-9 for the first time today,and It leaves me without usb storage it seems. I have a Macbook Pro 7.1, I chose default options in the install script, but set all 'Budget Fair Queueing' options/questions enabled. My USB mouse works, but when I plug in a memory stick no device is created in /dev/. With the default 2.6.35-ARCH and same boot options usb storage works fine. Any ideas?

a part of dmesg that seems relevant:

usb 2-1: new high speed USB device using ehci_hcd and address 2
usb 2-1: unable to read config index 0 descriptor/start: -71
usb 2-1: chopping to 0 config(s)
usb 2-1: string descriptor 0 read error: -71
usb 2-1: no configuration chosen from 0 choices

when I compare lsmod between the two kernels I do notice usb_storage is not loaded with the ck kernel. But even tjhough a 'modprobe usb_storage' does't give any errors I don't get a device in /dev/.

lsmod | grep usb:

usbhid                 36325  0 
hid                    76168  2 hid_apple,usbhid
usbcore               137506  5 bcm5974,usbhid,ohci_hcd,ehci_hcd

[edit]
seems to be not specific to the CK patchset, but a kernel bug in EHCI when used with the particular Nvidia 320M (MPC89) chipset: kernel bug 21182. The patch on that page fixes it for me.

How did you build the kernel? I notice the PKGBUILD has options for streamlining your module config. Perhaps it's a bit too streamlined?

rwd · 2010-11-07 23:23:05

I left the streamline option in the PKGBUILD disabled ('n'). The change I made to the pkgbuild was setting 'Budget Fair Queueing' to 'y'.

I'd say you should be trying testing/kernel26 if you want a fair comparison of how your hardware reacts. At least then you can pin it down to being a config issue or something more serious.

Booting from kernel26 (2.6.36-3) from testing gives the same error/problem indeed. Made a topic in 'testing'.
