I have applied Søren Schmidts fix(1) for this to my -stable system with
a VIA KT133A/686B (Jetway 663AS MB) and it has fixed my sure fire test case
(dd if=/dev/ad0 of=/dev/null bs=1024k - would crash after about 20Gb and make
funny noises rather earlier - now runs smoothly to the end of the 30Gb drive).
Question for Søren, I know of (via USENET) some people who seem to
be much more severely afflicted, is there any good reason why I shouldn't
offer them this as a patch ?
On a related note, the interface speed for this box seems to be around
47Mb/sec (using the 5 runs of dd the first half megabyte test), the drive is
an IBM DTLA 307030.
(1) OK workaround - it's the same code (via686b routine and conditional call)
as -current but in ata-all.c instead of ata-pci.c.
