boot freeze during pcmcia_socket : cs: IO port probe

Since I upgraded to 10.10, my nx9105 freeze at boot about 3 times out of 4.
The freeze happens early enough that nothing is recorded in any log.
using ignore_loglevel, it appeared that it was related to pcmcia / cardbus / yenta_socket.ko, and that the log lines preceding the freeze were most of the time looking like those:

Dec 19 09:26:09 Philinux kernel: [ 39.528596] yenta_cardbus 0000:02:04.1: ISA IRQ mask 0x0c30, PCI irq 18

with the freeze occuring on the last line above.
After many searches and attempts, it appeared that I could totally suppress the problem by blacklisting yenta_socket.ko.
