I completely missed the verification ping here in the sea of other kernel bug mail that I get. Will work with the LP team to get this verified as quickly as I can, but if you need to make a revert/ship call before I can, the patches should be pretty harmless even if they don't fix the bug, so I'd vote for keep and ship and we can fix later if we missed a bit. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1844155 Title: arm64: sigaltstack fails with MINSIGSTKSZ for 32-bit processes Status in linux package in Ubuntu: Confirmed Status in linux source package in Xenial: Fix Committed Status in linux package in Debian: Fix Released Bug description: [Impact] The arm64 kernel allows one to run aarch32 processes on an aarch64 processor, using the standard 32/64-bit syscall compatibility.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
