Hi, I just compiled 2.6.23-rc1-mm2 with libata for the first time. I chose CONFIG_ATA, CONFIG_ATA_ACPI and CONFIG_PATA_ALI. CONFIG_BLK_DEV_SD and CONFIG_BLK_DEV_SR are enabled, too.

But this time it always configures UDMA/25. I had to kill the mount process. Is this a problem with my drive? It works fine with alim15x3, so. Did I forget to enable something in the kernel?
