All that stuff about try_to_free_pages_zone, alloc_pages, and so on belongs to memory management. generic_file_write and text.lock.journal are part of ext3 (I think). However, it certainly could be that the ehci driver is causing a problem that doesn't show up until later. > I don't understand the intricacies, but if it all works fine at USB1.1 > speeds (and it does work flawlessly) but barfs when plugged in to a USB > 2.0 port does that not imply a problem with the ehci-hcd module rather > than usb-storage or ext3/MSDOS? Probably. I don't know anything about the intricacies of HCDs either. > Does the ehci-hcd module present a > subtly different view of the world to the usb-storage and fs modules > than just the usb-uhci modules by itself?

Enabling usb-storage debugging will probably help, at least a little, no matter what.
