Subject: igb patches needed for stable
Date: Thu, 10 Apr 2014 14:36:03 +0200 [thread overview]
Message-ID: <20140410143603.3df4f20c@skate> (raw)
Hello,
I just wanted to let you know that the following two patches:
cb06d102327eadcd1bdc480bfd9f8876251d1007 igb: Fix Null-pointer dereference in igb_reset_q_vector
b709323d2477614823a38c2f2a9a206e087e28fc igb: Unset IGB_FLAG_HAS_MSIX-flag when falling back to msi-only
should probably be backported to stable 3.14 versions. The above
patches are part of Linus tree, but merged after v3.14 has been
released. However, they fix a regression introduced by cd14ef54d25b
(igb: Change to use statically allocated array for MSIx entries), which
is part of v3.14.
And I'm actually experiencing a crash igb_reset_q_vector() on a system
which has MSI support, but not MSI-X support, and basically the code
path of the driver which fallbacks from MSI-X to MSI is the one
crashing. With both of these patches applied on top of 3.14, my igb NIC
works fine.
Best regards,
Thomas
