Scary.
Now bugzilla.kernel.org is down, so we have to make do with whatever
made it to the mailing list archives search engines can find.
Bug 7264 seems interesting. Apparently v2.6.17-rc1~998^2~45 (PCI:
quirk for IBM Dock II cardbus controllers, 2006-01-17) introduced an
interrupt routing fix which v2.6.19-rc6~20 (revert "PCI: quirk for IBM
Dock II cardbus controllers", 2006-11-14) needed to revert.
I wonder if v2.6.34-rc2~30^2~2 (pcmcia: re-route Cardbus IRQ to ISA on
ti1130 bridges if necessary, 2010-03-06) improved things. Thomas,
would you be able to try a more recent kernel?
Sorry for the trouble and the very slow response,
Jonathan
