2.5.58+bk: ejecting a pcmcia card: sleeping function from illegal ctx

[Alex Riesen]

I tried to eject a PCMCIA card (WLinx 10/100, using pcnet driver)
from this notebook, and got the trace below.
No ill effects besides that noticed, but i didn't tried to
insert the card back, just shut down the system.

All I'll say at this point is "known problem, fix in progress".
