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

[Yaroslav Halchenko]

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
