Hi Andre,
I found the problem - probe for ide4 caused switching HT-6560A chip
to wrong non-operational mode. Address of its control register is
0x3e6, it is the same as alerrnate status register of ide4.
It is bad that it is not possible to use request_region() function to
reserve this io port to ht6560 because chipset drivers are called too
early.
And why older ide patches worked for me? Because of some bug they
caused that ide1 to ide5 showed "ports already in use" and so were
not autoprobed.
So ide4=noprobe works. I tried it even before, but I had too long
kernel command line and this directive was truncated. And as linux
did't booted, I didn't see the truncated line. Anyway - what is the
maximum length of kernel command line? My was truncated to 46 usable
characters, isn't it too few?
Regards,
Petr Soucek
