The following reply was made to PR usb/81621; it has been noted by GNATS. From: Michael Schout <mschout@gkg.net> To: bug-followup@FreeBSD.org, gerrit@pmp.uni-hannover.de Cc: Subject: Re: usb/81621: external hd hangs under load on ehci Date: Mon, 10 Oct 2005 10:11:52 -0500 I have a VIA chipset as well, and the patch in the link above (posted by Rojer, that adds the EHCI_SCFLG_LOSTINTRBUG workaround), fixes all of the problems with my chipset. Without this patch, my system will hang and/or panic every single time a USB 2.0 device is used for more than a few seconds. I've been using the patch for 2 weeeks now with no problems at all and ehci/USB 2.0 devices work perfectly now. My controller is a VIA VT6202. Regards, Michael Schout
