Good day! A couple of weeks ago i begun meeting with system hangs and arbitrary reboots. It occurs when some intensive traffic come into play with using mobile usb modem. After i move to todays RELENG_7 (from ex-7 -CURRENT) i saw this message after arbitrary reboot in /var/log/messages: Oct 13 23:54:04 nx7400 syslogd: kernel boot file is /boot/kernel/kernel Oct 13 23:54:04 nx7400 kernel: panic: uhci_abort_xfer: not in process context Oct 13 23:54:04 nx7400 kernel: cpuid = 0 Oct 13 23:54:04 nx7400 kernel: Uptime: 2h53m44s Oct 13 23:54:04 nx7400 kernel: Physical memory: 747 MB Oct 13 23:54:04 nx7400 kernel: Dumping 147 MB: 132 116 100 84 68 52 36 20 4 Oct 13 23:54:04 nx7400 kernel: Dump complete Oct 13 23:54:04 nx7400 kernel: Automatic reboot in 15 seconds - press a key on the console to abort Oct 13 23:54:04 nx7400 kernel: --> Press a key on the console to reboot, Oct 13 23:54:04 nx7400 kernel: --> or switch off the system now. Oct 13 23:54:04 nx7400 kernel: Rebooting... This panic is initiated if (xfer->device->bus->intr_context || !curproc) in uhci_abort_xfer(). What i can do to eliminate such situations or what i do wrong? My system is FreeBSD 7.0-PRERELEASE i386 GENERIC from todays cvs. Thanks in advance for answer.
