Subject: RE: [git patches] libata fixes

Just one point that may be interesting, as it seems that this is IRQ
related : at the beginning of the dmesg, it seems that IRQ16 is used
for sky2/Yukon , but when reading /proc/interrupts, it has been remapped
to IRQ 505... Could this also affect libata ?

Regards,
Paul
