RE: kernel lockup on 6.0 beta2 on cardbus insertion on Dell Inspiron 9100 laptop

[John Refling <mpweadh%hotmail.com@localhost>]

bar_tag=da525b1c
bar_size=131072
len=2048
bar_memh=db230000
cis_ptr=da525b20
tuples=0

This is with the new code in the "+" diff.  I suspect if I hard code 512
into len, it won't crash.

How to build 512-hack?  Didn't see that in the config area.  Already set the

#option PCMCIAVERBOSE

in the kernel build, but can set anything you want.

Was booting with -12d

And where to set the pcmciacis_debug ?.  At the shell or ??

Probably need to take a nap now.   3:30 AM here.  Back later...

Can you please add printfs and tell us what values bar_size, cis_ptr and len
have?

Can you build a kernel (with the 512-hack) with PCMCIACISDEBUG, boot -d
and set pcmciacis_debug to 1? This should dump all of the CIS on the
card.
