The following reply was made to PR kern/111743; it has been noted by GNATS. From: Bob Frazier <bobf@mrp3.com> To: bug-followup@FreeBSD.org Cc: Subject: Re: kern/111743: [ath] if_ath occasionally hangs system with certain broadcom AP chipsets Date: Mon, 23 Apr 2007 09:42:41 -0700 additional information: when in console mode (X11 not running) the following differences in bug behavior were noted: a) keyboard input would not work for login screens nor for 'logged in' shell; however, the ALT+F# keys would still work to switch virtual screens, as well as caps lock and num lock. b) when X11 is running, the mouse and keyboard do not function at all (including CTRL+ALT+F# keys and CTRL+ALT+BACKSPACE) c) after removing the cardbus card for the atheros card, in either case the system truly does 'hang'. This test was conducted using a new kernel build from source (6-STABLE), obtained via cvsup on 4/21/2007 Tests were also conducted while a USB serial device (uplcom driver) was loaded. Here is a typical 'kldstat' for this system, which should have been included in the original bug report: Id Refs Address Size Name 1 23 0xc0400000 71cd88 kernel 2 1 0xc0b1d000 32e4 splash_bmp.ko 3 1 0xc0b21000 4228 vesa.ko 4 3 0xc0be6000 1c550 linux.ko 5 1 0xc0c03000 6170 snd_via8233.ko 6 2 0xc0c0a000 22c48 sound.ko 7 1 0xc0c2d000 5ae18 acpi.ko 8 1 0xc50ee000 6000 linprocfs.ko 9 1 0xc5520000 2000 rtc.ko 10 1 0xc5641000 4000 uplcom.ko 11 1 0xc5645000 3000 ucom.ko 12 1 0xc5d3c000 1b000 smbfs.ko 13 2 0xc55de000 3000 libiconv.ko 14 2 0xc55e4000 3000 libmchain.ko The bug was repeated with a 300N device functioning correctly at close range (3 feet from the client). It appeared in console mode after several successful scans, after which the keyboard stopped responding.
