Subject: Re: BUG: SDHCI fails to DMA-unmap, and other warnings
Date: Thu, 17 Dec 2015 22:00:45 +0000 [thread overview]
Message-ID: <20151217220045.GA27072@n2100.arm.linux.org.uk> (raw)
In-Reply-To: <20151217215140.GK8644@n2100.arm.linux.org.uk>
And another one:
"mmcblk0: retrying because a re-tune was needed"
static int mmc_blk_err_check(struct mmc_card *card,
struct mmc_async_req *areq)
{
...
if (brq->data.error) {
if (need_retune && !brq->retune_retry_done) {
pr_info("%s: retrying because a re-tune was needed\n",
req->rq_disk->disk_name);
brq->retune_retry_done = 1;
return MMC_BLK_RETRY;
This looks like it'll spam the kernel log regularly if MMC/SD is used
heavily with a UHS card, which (iirc) requires regular retunes. Why is
this message at info level, and not debug level?
