Here's some information, relevant to the recent "Re: Keyboard is frozen
on boot of 2.3.41" thread in linux-kernel.
In short:
I am not having conflicts with keyboard or mouse in 2.3.41, but kapmd is
dead-on-arrival. I'll be glad to help test any code that might help.
Building PCMCIA and Cardbus support into the 2.3.41 kernel allows
detection of the TI 1251A PCI-Cardbus controller (Thinkpad 390E laptop),
and it allocates IRQ 5 to that purpose, but insertion of a 3Com
3CXFE575BT (10/100 Mb/s ethernet) card reliably locks the machine up
solid.
However...
More curiously, kernel PCMCIA seems to cripple kapmd (during a suspend
operation, the machine spews addresses to the console in an apparent
infinite loop while never actually suspending the laptop). Additionally,
applications that look at APM, like wmapm, cause kernel oopses and
segfault. 2.3.41 kapmd functions happily _without_ PCMCIA built
into the kernel.
I have included the relevant portions from /var/log/messages in the
hopes that they may be useful. Note: all PCMCIA client drivers are
compiled as modules, CONFIG_PCMCIA=y, CONFIG_CARDBUS=y, CONFIG_I82365 is
not set and CONFIG_TCIC is not set.

At this point, the machine was completely frozen.
It is relevant to note that both PCMCIA and APM play happily together in
kernels as late as 2.3.35, before the major PCI and Cardbus changes.
I'd be very glad to test any code anyone would like to apply to this
problem, and will look at the code myself by the weekend.
