interesting, I see the same thing except it hangs not before the disk
drives are initialized but afterwards, when initializing the CD-ROM
drives. (Compiling ide-cd as module permits successful boot but hangs
on insmod). This is with SiS5513 rev 208 IDE function from SiS5591
chipset with CONFIG_BLK_DEV_SIS5513 and autotune enabled (default).
For me, the workaround is disabling either one of the above (i.e. not
including SiS5513 support in the kernel or append'ing "hdx=noautotune"
for the cdrom-drives) and everything is fine again. You may want to use
hdparm to get udma2 working. Doing so provides relyable >14MB/s for a
5.4kRPM drive in UDMA(33), so my impression is this is only a tuning
issue.

I'm not absolutely sure, but I'm wondering why the driver enabled all
BAR's including the relocateable port areas which are useful in native
mode only. IMHO the driver should force compatibility mode. For me, only
the last BAR containing the BM registers at 0xd000 is enabled.
