Message-ID: <957323.87386.qm@web52909.mail.yahoo.com> Date: Sat, 20 Jan 2007 23:06:57 +0000 (GMT) From: Chris Rankin <rankincj@...oo.com> To: linux-kernel@...r.kernel.org Cc: netdev@...r.kernel.org Subject: [BUG] Sleeping function called from invalid context (2.6.18.6) Hi, I have been testing my wireless zd1211rw driver with kismet, but have noticed my logs filling up with these messages instead: BUG: sleeping function called from invalid context at kernel/mutex.c:86 in_atomic():0, irqs_disabled():1 [<c029688e>] mutex_lock+0x12/0x1a [<c02496ae>] netdev_run_todo+0x10/0x1f1 [<c024a148>] dev_ioctl+0x465/0x497 [<c01626ff>] d_rehash+0x47/0x78 [<c0240379>] sock_attach_fd+0x6c/0xcb [<c023fc9d>] sock_ioctl+0x0/0x1b3 [<c015e508>] do_ioctl+0x1c/0x5d [<c015e78a>] vfs_ioctl+0x241/0x254 [<c015e7c9>] sys_ioctl+0x2c/0x43 [<c0102c3f>] syscall_call+0x7/0xb According to the comment in linux/net/core/dev.c * 2) Since we run with the RTNL semaphore not held, we can sleep * safely in order to wait for the netdev refcnt to drop to zero. Well, apparently we can't sleep safely after all because IRQs have been disabled. Cheers, Chris ___________________________________________________________ New Yahoo!
