Whenever I load the ehci-hcd driver for my USB2 card, I get the following
(kernel 2.4.22):

Dec 1 11:28:58 mwatts kernel: usb.c: USB disconnect on device 02:07.0-1
address 2
Dec 1 11:29:19 mwatts kernel: ehci_hcd 02:07.2: VIA Technologies, Inc. USB
2.0
Dec 1 11:29:19 mwatts kernel: ehci_hcd 02:07.2: irq 18, pci mem e0ab9c00
Dec 1 11:29:19 mwatts kernel: usb.c: new USB bus registered, assigned bus
number 5
Dec 1 11:29:19 mwatts kernel: PCI: 02:07.2 PCI cache line size set
incorrectly (64 bytes) by BIOS/FW.
Dec 1 11:29:19 mwatts kernel: PCI: 02:07.2 cache line size too large -
expecting 32.
Dec 1 11:29:19 mwatts kernel: ehci_hcd 02:07.2: USB 2.0 enabled, EHCI 0.95,
driver 2003-Jun-19/2.4
Dec 1 11:29:19 mwatts kernel: hub.c: USB hub found
Dec 1 11:29:19 mwatts kernel: hub.c: 4 ports detected

Is the stuff about the cache line normal?

Also, I get massive amounts of errors whenever I try and do anything to a
20Gig drive connected via usb2 (fat32 filesystem)
If I simply unload the ehci-hcd driver, it works fine in usb1 on the same
hardware (lspci -v follows).

This is what happens when I plug in the drive:

After a few more errors, the drive will eventually be marked offline again.
