Public bug reported:
I have older server motherboard Supermicro P3TDDE, with additional IDE
controller Promise PDC20267 (FastTrak100) on it. Once I tried to install
Ubuntu 9.04 onto the disk attached to this controller, and failed.
libata driver is able to detect the controller, identify the hard drive
and read partition table from it, but with following read/write activity
on this drive, errors start to occur. In dmesg I can also see drive
speed decreasing from UDMA100 to UDMA66, 33 and PIO4. Then it becomes
impossible to read/write to the drive at all.
So far I use Ubuntu 8.04 with kernel 2.6.24 on this system. With it, the
drive is detected and operated completely well. This kernel uses older
driver version for IDE subsystem, so the drive is detected as /dev/hde,
not /dev/sda. Did not try Ubuntu 8.10 so far. May be something wrong
happened during porting old Promise driver from IDE to libata. As I
heard, SUSE still use older IDE driver in their kernels for old Promise
controllers support. May be Ubuntu should turn on similar option. It
seems this is an upstream bug, to be also reported to kernel.org folks.
