Hi there, over the last months I have been experiencing kernel panics from time to time on suspend / resume of my Lenovo T420s laptop. Reading the backtrace it seems that my wireless modem is involved. As the machine locks up completely, I have to manually copy the backtrace, so please excuse any possible typos: ... page_fault ? __ticket_spin_lock default_spin_lock_flags _raw_spin_lock_irqsave tty_port_hangup acm_tty_hangup [cdc_acm] __tty_hangup ? __tty_hangup do_tty_hangup process_one_work worker_thread ... The WWAN modem in question is a Lenovo-branded Ericsson F5521gw HSDPA modem. lsusb output is available at: https://secure.tgbyte.de/dropbox/quei4IVa.txt $ uname -a Linux orion 3.1.0-030100-generic #201110241006 SMP Mon Oct 24 14:07:10 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Not sure if this is related to: http://groups.google.com/a/chromium.org/group/chromium-os-reviews/browse_thread/thread/5bced36ebfb6f0b8?pli=1 Thanks for your help!
