Message-Id: <200810251118.14714.borntraeger@de.ibm.com> Date: Sat, 25 Oct 2008 11:18:14 +0200 From: Christian Borntraeger <borntraeger@...ibm.com> To: Jens Axboe <jens.axboe@...cle.com> Cc: LKML <linux-kernel@...r.kernel.org> Subject: WARNING: at drivers/ata/libata-eh.c:664 (and others) with 2.6.27-05178 Hello Jens, while doing a backup on DVD+R I got the following warning (and a k3b hung). the drive is a Plextor 716A on a jmicron PATA port. I have never seen this with earlier kernels. I am a bit reluctant to reproduce or bisect this problem, since it might kills my blank DVDs. Could this be related to commit e013e13bf605b9e6b702adffbe2853cfc60e7806 (libata: fix bug with non-ncq devices)? Thank you for any idea.
