[linux-usb-devel] status of usb-ohci on cache incoherent systems
Hi, I've read some older discussions in this list about USB problems on cache incoherent systems (e.g. ARM, PPC). What is the status on this? We are using the 2.4.21 linuxppc_2_4_devel tree from the bitkeeper repository. This kernel still has problems with USB. At least some device drivers habe problems (usbmouse, usb-storage). Are there any current fixes or is anybody working on a general solution?

Re: [linux-usb-devel] Problem with AIPTEK usb-pendrive
Hi, it seems that our problem with the USB-pendrive is easy to explain, but not difficult to solve: We are using a ohci controller on a cache-incoherent system (IBM PowerPC 405). This causes a lot of problems in the USB system during DMA'ing to non-cacheline-aligned memory regions.

Hi Alan,

mount -t ext2 /dev/sda1 /mnt does not return
Have you tried mounting it read-only? Also, can you tell where the mount
process is hung? Try Alt-SysRq-T (and make sure you have enabled the
Magic SysRq key in your kernel).
Since my system is an embedded platform without keyboard, I can only post a strace
output
from the mount command. As you can see, the call blocks in the open systemcall on the
/dev/sda1 device.
When I interrupt the strace/mount with CTRL-C the open() call is interrupted
unfinished.
Without strace the mount call cannot be interrupted by CTRL-C.
