Hmm... I like the workaround but wish the kernel weren't generating
the above output. How about doing something like the following?
svia_error_handler()
{
if (workaround hasn't been applied yet &&
the conditions match for the workaround) {
apply the workaround;
mark as such;
print informational message;
set ATA_EHI_QUIET;
}
ata_sff_error_handler(ap);
}
