[EciAdsl 3/5] Synchronization... ERROR reading interrupts *** glibc detected *** double free or corruption (fasttop): 0x0804f158 *** /usr/bin/eciadsl-start: line 517: 11399 Abortito "$BIN_DIR/eciadsl-synch" $synch_options ERROR: failed to get synchronization usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd eciadsl-synch rqt 192 rq 222 len 13 ret -110 tried 3 times, always the same. so i manually unplugged modem and replugged. works perfectly (as usual). seems a problem on suspending and resuming attached device. i've access to eciadsl cvs so i can patch it. the first problem (no suspend) i think can be fixed binding some signals in userspace, which? the second seems an init problem, that i leave to you :) Patrizio ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
