Subject: PROBLEM: sk98lin misbehaves with D-Link DGE-530T which doesn't have readable VPD
Date: Fri, 09 Sep 2005 11:49:45 -0600 [thread overview]
Message-ID: <4321CB39.3080206@lanl.gov> (raw)
In-Reply-To: <42EE9721.5000501@lanl.gov>
Driver sk98lin makes repeated attempts to read VPD even after the first
VpdInit() fails. This is wrong.
Lots of people seem to be getting repeated "Vpd: Cannot read VPD keys"
errors. When nifd is active, this can happen every second, causing
kernel stalls that disrupt time-critical operations (e.g. DVD use).
Inexpensive cards like D-Link DGE-530T may lack a readable VPD, so there
is no point in trying to access this missing feature and causing brief
system stalls (see
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=136158).
Can sk98lin be enhanced to give up on VPD after the first VpdInit()
fails? The NIC appears to operate stably even without a readable VPD.
I haven't tested the experimental driver skge, but the same comment may
apply. Obviously it makes no sense to repeatedly look for VPD keys when
the VPD is missing or incorrect.
Sincerely,
Josip
