Subject: 2.6.19-rc1: PATA long delay with AMD driver on init

Hi,

I tried the PATA driver for my onboard IDE with one DVD+RW drive connected as 
master. The driver hangs a long time on probing (and causing major havoc on 
the rest of my devices). Using the old IDE driver I don't have this problem.

I deactivated one SATA and secondary IDE controller. Enabled the situation 
gets worse.

The kernel is patched with reiser4 and acpi_skip_timer_override quirk is 
deactivated (see last link why).

I tried different combinations (dmesg + .config). Differences are mostly pci 
mt init, irqpoll, nforce eth napi, pata/ide amd driver
