This is on a Toshiba Portege 3110CT laptop.
tiny:~# lspci | grep IDE
00:07.1 IDE interface: Intel Corporation 82440MX EIDE Controller
Works fine with 2.2.14, 2.2.16pre7 and 2.3.99-pre[1-6], very stable
even with hdparm -u1 -c1 and idebus=66. Transfer rate by hdparm -tT
is about 11Mb/s.
I've tested this with every kernel since 2.3.99-pre6 (last attempt
was 2.4.0-test1-ac8) with PIIX support turned on and off, but the
result is a bus reset after some use (and subsequente fs
corruption). Spontaneous reboots during disk access and other
lockups also happened in some cases.
Turning dma off (hdparm -d0) does solve the problem, but also gives
me half the transfer rate. And, it works on older kernels :). BTW,
I'm also running 2.4.0-test1-ac8 on another laptop (an old ISA-based
Toshiba Satellite Pro 430CDT) with no problems, but that controller
doesn't support DMA.
Here are some dumps from syslog with pertinent information:
