No output. I built a kernel.debug, too. Booting in verbose mode, with hw.cbb.debug=1 hw.pccard.debug=1 hw.cardbus.debug=1 hw.pccard.cis_debug=1 hw.cardbus.cis_debug=1 hw.wi.debug=1 I have the same messages. Well, not exactly the same: this time there is not the "Bad Vcc request" error but the pcmcia slot still not works. I think there is no way to increase the debug level. I peeked at the sources in dev/pccard/pccard.c dev/cardbus/cardbus.c dev/pccbb/pccbb.c but those TUNABLES seem to be only flags. I mean: putting hw.pccard.debug=1 or hw.pccard.debug=3 doesn't change anything. In pccbb.c there are two o2micro_power_hack() functions. Maybe O2Micro Controllers are not well supported at the present time. I'm going to put some printf around in order to have more information about those variables and structs, but honestly I have no idea of what they mean. > in case nothing happend, reboot the machine without acpi and see if you > get the same behaviors. Disabling ACPI the machine goes in kernel panic while booting. According to acpi(4) it's possible to disable only some acpi sub-drivers via "debug.acpi.disabled" environment variable. I'll try these tricks. -- http://swpat.ffii.org/ Giuseppe _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
