Sad IRQ11 conflict causing cardmgr startup problems on 3110CT ToPIC100 ? 

Forum: PCMCIA on Toshiba laptops

On a Toshiba Prtege 3110CT with a ToPIC100 rev 20 if CardServices are started after the network, the system freezes.
By pressing the reset button (in `resume' mode) and doing three to five `suepend + resume' cycles, things recover.
The problem appears to relate to IRQ 11 being shared by the eepro100 LAN interface on the IO adaptor.
Should it be possible to share IRQ 11 ?
Can one of them be moved to another IRQ ?

A HACK is to start CardServices before the network.
Is there a problem with doing this ?
