While testing an EM28xx based USB DVB stick which I've recently acquired, I find that occasionally the driver stops responding after it returns -EFBIG from one of its ioctls. I've no idea whether there's a previous kernel version which works.
Finding the EFBIG return in ehci-sched.c, I decided to make the debug a little more verbose there, and got: ci_hdrc ci_hdrc.0: request e7668800 would overflow (4093+63 >= 4096) So, I augmented it, which revealed: ci_hdrc ci_hdrc.0: request ecd75000 would overflow (4090+64-1 >= 4096+0) ci_hdrc ci_hdrc.0: hs 1 xfer_flag 0x206 empty 1 new_stream 1 now 1032 next 4090 base 1040 Here, start = 4090, period = 1, span = 64, mod = 4096, wrap = 0. This looks fairly complex to debug - any suggestions on how to debug this further?
