I think it's somehow related to the td processing. I'm getting a lot of "bad entry" messages from ohci-q with 2.5.42 and usbtest. With and without sglist. I've another piece of code which streams both in and out using a pool of urbs. It works 100% stable with 2.4.20-pre8 but usually fails with 2.5.42 within seconds reporting "bad entry". I't looks to me like some kind of donelist corruption but might be td hashbin or pci_pool as well. Maybe the output below would tell you something. It was obtained during re-enumeration after firmware download where a firmware bug caused the device to hang in the GetDescriptor request. I've no idea if this is related to Lars's problem, but I've also seen this happen during reboot with the FX+broken firmware still connected.
