Created attachment 330500 [details] b44_WOL_setup_one-bit-off_stack_corruption_kernel_panic_fix.patch I sent this fix to LKML: http://patchwork.kernel.org/patch/64261/ http://lkml.org/lkml/2009/12/2/193 Note: Even if this problem does not cause stack corruption in SLE11 and SLE10 (and maybe SLE9), this problem also affects these products. Michal, what exactly should be done to get this fix to openSUSE 11.2 and SLES? If the kernel is compiled with stack-protector then it fixes stack corruption kernel panic and WakeOnLan. If the kernel is compiled without stack-protector then it fixes WakeOnLan and possibly invisible stack corruption. You posted it upstream with a Cc: stable@kernel.org. I think you don't have to do anything, it should appear a 2.6.31.y stable kernel release, which we are tracking for updates. (In reply to comment #4) > You posted it upstream with a Cc: stable@kernel.org. Greg should also pick this up for 2.6.27 for SLE11. I will check back on his queue in a few days to see if it got picked up. Checked into SLE11_BRANCH. Confirmed in SLE11-SP1 via patches.kernel.org/patch-2.6.32.1-2 Greg- Any idea why this didn't get picked up for 2.6.27 -stable? Upstream this is e0188829cb724e7d12a2d4e343b368ff1d6e1471 No idea, I've now queued it up for the next .27-stable release |
Created attachment 329127 [details] b44_panic.jpg I experience kernel panic during the system shutdown. It happens in about 50% of all shutdowns. This is the first time it crashed with the right vt in front, so I was able to make screenshot.
