PCMCIA modem not found... resume/suspend helps some times... magic is not found

Wed Jul 5 17:49:43 EDT 2006

Dear PCMCIA People,

Unfortunately for me I've just now discovered proper mailing list to
acquire about my problem with PCMCIA modem I am trying to make work
under 2.6.17-mm4

The issue is that it is not found at all:

> pccardctl status
Socket 0:
  5.0V 16-bit PC Card
  Subdevice 0 (function 0) [unbound]
> pccardctl info
PRODID_1=""
PRODID_2=""
PRODID_3=""
PRODID_4=""
MANFID=0000,0000
FUNCID=255

only once after I've done way too many dancing around, suspend/resume
sequenece brought it online. I could not bring it up any time after.
Now I am just getting following debug information without proper
identification of the card, and thus no binding to serial_cs which is
loaded. Please advise where should I look to figure out "why?". Thank
you in advance

Dear Kernel People,

Since nobody followed up I've decided to provide additional information
which might help to pin point the problem.
I've loaded pcmcia_core with pc_debug=255

Troublesome lines for me are:

Jul  5 15:52:25 vaio kernel: pcmcia: registering new device pcmcia0.0
Jul  5 15:52:25 vaio kernel: cs: pcmcia_socket0: cs: overrun in pcmcia_get_next_tuple
Jul  5 15:52:26 vaio kernel: cs: pcmcia_socket0: cs: overrun in pcmcia_get_next_tuple

Full kern.log is available from
http://www.onerussian.com/Linux/bugs/pcmcia.modem/kern.log.debug

Please advise what else could I do to revive this modem to life

Thank you in advance
