David,
Thanks for the patch. I applied it against 2.4.21-pre4-ac6 and found that writing to the USB 2.0 HDD on the VT8235 was still perfect, but the computer would still hang (lock up completely) after reading the same amount of data from USB 2.0 HDD.
So what did the statistics say about lost interrupts on your VT8235 hardware? And I'm not sure what's in "ac6", but pre5 with that patch I sent this AM is what I call current (and it includes these two tweaks) for 2.4 users.
It's been quite a while since VIA would "lock up" hardware in my testing. Lately it's not even hiccupping for me, won't even wedge a single process. (Though more VT6202 testing would surely be good). So I'm surprised you imply nothing changed on the 2.5 kernels.
I've had it running with a bunch of "usbtest" cases for the last day ... those put a mix of read and write loads (high speed in this case). It ran several hours of disk testing before that (including "mkfs -c"). Those things have been intermittently troublesome on VIA.
What kind of differences did it make for you? Did it improve speed and/or reliability on storage devices (on both reading and writing?)?
An intermittent storage failure appears to be gone (though maybe it just got hugely more rare), and "hdparm -tT" won't act slow on 2.5 for me (or wedge wierdly).
- Dave
