Might be handy > for debugging PM stuff. >=20 thanks for that information, you also had a patch for checking pm which was explicitely marked as not-to-merge. Is there any up-to-date version of it? Well, for debugging I check first average currents via bq27000 attached to omap_hdq. omap_hdq gets stuck after first transaction after idling uarts which does not happen when CM_AUTOIDLE1_CORE.AUTO_HDQ is cleared. Reloading the omap_hdq module to try to fix things makes w1 really freak out (patch already sent for that). Well, will do some rtfm and hopefully come back with a patch. afaicr there was something special... The result are power management problem in /dev/brain ;-) Regards, Andreas --Sig_/U736Hjz4msrhS5TIRMcCICx Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE7sDbhY5mwNpwYgrAfb1qx03ikyQFAlupxwwACgkQfb1qx03i kySfrhAAl4iNzNHtUh9FwtewvuB/4HVtX5zn/mbujKtPE3pQnKPLtpn4UNkLJQZU OaymyjkUnbPl6Y2ZO7G1ASZ6kBy7xC2FXaSgkrITTe8Sc7V1HsNxUX84OKiAo1QC EMliiQNZwY3KT0+hHVrA9JboV4J5bM6LJ/OwUbsfuBHZzffZOx4KtrebSj/5Rljy Emip5N3mbsa/k2tAPsRAOFovMSWt0t2IeXpKHomoRP353Nzkz3B4a/LFTZeci8sO f8gOJvKbZ+7+AItXhrRHnIrSqmSCqZW1ugz9Z1M9F6S1DQpWmfhX0ra/QyLPNQ40 2gRD7kp5wum99lhs1AzXuwtOvA9nWSxMd69WiSQlYWam2usDdi30bLDLufQGhD0f CWWIFEcfV/sakACkaePh9C6Q2gWUVxPZuTj1PwVoy6gLk/vDC+v7/YgZCaQKEYSY vlcwKfvALa9baYtmUl87j046A6WbrA5A20GAfz1BUCIbLfY7n7SnA032OzLzlbZK r78UdX+vXkMCBvzZAUK5qUzmlWxS0jv6RkW0xY/o/I3YCpVLPJlGLdTIMDYQ+MEH oI430AMe6DbDKGjczeaMldunNcmrBj9Lw/nWx1bP0jKQNVHVdeoGRmcQKNBS0q4w 8D8lhwE2JLy27c5Fc/Ch4LWTEjaQ6ExVs4Gk4IPq+9cZ7T0Y46U= =px2V -----END PGP SIGNATURE----- --Sig_/U736Hjz4msrhS5TIRMcCICx--
