Hi, I've finally got around to test latest kernels and managed to find a bug in the serial subsystem, which happens during suspend.
I use a 3Com PC Card Bluetooth adapter that needs serial_cs and hci_uart modules. Whenever I try to suspend using 2.6.10 or a newer kernel, the following bug appears. Note that 2.6.9 works perfectly. #v+ handwritten, 2.6.11-rc5 kernel BUG at drivers/serial/8250.c:1256! invalid operand: 0000 [#1] PREEMPT [...] EIP is at serial_unlink_irq_chain+0x4b/0x60 [8250] [...] Call Trace: uart_suspend_port [serial_core] serial_suspend [serial_cs] serial_event [serial_cs] send_event_callback [pcmcia] __bus_for_each_dev bus_for_each_dev send_event_callback [pcmcia] send_event [pcmcia] send_event_callback [pcmcia] handle_event [pcmcia] ds_event [pcmcia] send_event [pcmcia_core] socket_suspend [pcmcia_core] #v- Photos are available here (sorry for the quality): http://hell.org.pl/~sziwan/bug_8250-1.jpg http://hell.org.pl/~sziwan/bug_8250-2.jpg http://hell.org.pl/~sziwan/bug_8250-3.jpg I'll be happy to provide whatever information is needed.
