nf7 and ehci

[Andriy Gapon]

Has anybody had a successful experience with ehci and nf7 (or nforce2 in
general) on 5.2.1 or later ?
I compiled ehci into a kernel and everything was pretty fine (i.e
probing, attachment of devices) until I actually tried to copy a large
file from a compact flash card - cp froze, I couldn't kill it and the
following message started to run on console:

umass0: BBB reset failed, TIMEOUT
umass0: BBB bulk-in clear stall failed, TIMEOUT
umass0: BBB bulk-out clear stall failed, TIMEOUT
umass0: BBB reset failed, TIMEOUT
umass0: BBB bulk-in clear stall failed, TIMEOUT
umass0: BBB bulk-out clear stall failed, TIMEOUT
...


Here's ehci boot message:

Here's EHCI device pciconf (without ehci driver):

Umass device I used is 6-in-1 TravelFlash from PQI, detected as:
