Yes, rev 51 means VT 6202. Certainly troublesome, all along.
The VT 8235 (in southbridge) should be getting pretty usable.
kills 2.5.59 stone cold. Total lockup. 2.4.21 works flawlessly.
I am puzzeled. Is this a known problem?
UP Athlon, VIA chipset, storage driver _not_ loaded.
No, it's odd. Haven't heard of such problems before. Does it
reproduce on 2.5.59 plus the ehci-0122 patch ... which is now
Are you refering to your patch from 2003-1-31? That's included.
What 2003-1-31 patch? I see you have (MemWINV"+" vs "-") either:
- 2.5.59 plus the ehci-0122 patch, or
- 2.4.21pre plus analagous ehci24-0201 patch.
I'm unclear whether you're reporting the latest code made something
better on 2.4, or worse on 2.5 ... I know that in my testing, truly
nasty failures are getting a lot harder to come by, except with the
VT 6202 devices. (Maybe worth blacklisting them until a fix becomes
available -- a couple lines of code would forestall nastier problems,
at the price of slower i/o.)
Of course, I've never seen such a Genesys device, and it'd not be
unheard of for new hardware to kick in failure modes that haven't
been noticed before.
