Subject: [Bluez-devel] bug in hci_uart_tx_wakeup() causes panic when UART removed
Date: Sun, 26 Feb 2006 15:59:35 +0100 [thread overview]
Message-ID: <20060226145934.GA18327@hell.org.pl> (raw)
Hi,
Under specific circumstances, hci_uart_tx_wakeup() seems to call
tty->driver->write() without checking if the tty is alive, which
effectively causes a nasty panic in uart_write(). From what I've read so
far it seems that hci_ldisc.c is to blame, so I'm reporting it here.
