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