Subject: WARN_ON() in drivers/ata/libata-core.c:5211 ata_qc_issue
Date: Tue, 20 Apr 2010 16:16:16 +0200 [thread overview]
Message-ID: <20100420141616.GP4586@mail.wantstofly.org> (raw)
On mvsas, when I issue a SMART command (smartctl -a) while a dd
from /dev/sda to /dev/null is in progress, I hit the following
WARN_ON_ONCE in ata_qc_issue():
if (ata_is_ncq(prot)) {
WARN_ON_ONCE(link->sactive & (1 << qc->tag));
if (!link->sactive)
ap->nr_active_links++;
link->sactive |= 1 << qc->tag;
} else {
WARN_ON_ONCE(link->sactive); <===============
ap->nr_active_links++;
link->active_tag = qc->tag;
}
This is on 2.6.34-rc4 ish.
