Hello,
I own a PCI-Express parallel card installed on my server Fujitsu TX100
S2. I am running CentOS 6 x64. In Kernel version
2.6.32-71.29.1.el6.x86_64, it was correctly detected as:

To be able to load it I had to configure the file
/etc/modprobe.d/parport_pc.conf with the line "options parport_pc
io=0x2018"
Nevertheless, in CentOS the new kernel 2.6.32-131.12.1.el6 was released
and I have lost all compatibility with this PCI-Express card. Now, if I
execute an lspci -vv a message with the text "!!! Unknown header type
7f" appears
If I downgrade to 2.6.32-71.29.1.el6.x86_64 the card is recognised and
starts to work again.
Can you please help me in any way? do you know if is it maybe a bug or
only unsupported hardware in new kernels?
Best regards,
