Package: src:linux Version: 4.3.3-7~bpo8+1 Severity: important Hi,
I keep getting soft lockups (which essentially render the machine unusable) with this kernel ; my storage is a raid10 set of spinning rust SATA disks. The console log messages are of the form: NMI watchdog: BUG: soft lockup - CPU#1 stuck for 22s! [md0_raid10:182] I have no such problems with jessie's kernel (3.x) I tried googling the error message, but that suggested that the bug should have been fixed in 4.2. [this bug report is written on a similar machine with identical software installed; the affected machine isn't usable enough running this kernel] Regards, Matthew -- Package-specific info: ** Version: Linux version 4.3.0-0.bpo.1-amd64 (debian-ker...@lists.debian.org) (gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP Debian 4.3.3-7~bpo8+1 (2016-01-19) ** Command line: placeholder root=/dev/mapper/guests-root ro quiet ** Not tainted -- System Information: Debian Release: 8.3 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-backports'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.3.0-0.bpo.1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages linux-image-4.3.0-0.bpo.1-amd64 depends on: ii debconf [debconf-2.0] 1.5.56 ii initramfs-tools [linux-initramfs-tool] 0.120 ii kmod 18-3 ii linux-base 3.5 Versions of packages linux-image-4.3.0-0.bpo.1-amd64 recommends: ii firmware-linux-free 3.3 ii irqbalance 1.0.6-3 Versions of packages linux-image-4.3.0-0.bpo.1-amd64 suggests: pn debian-kernel-handbook <none> ii grub-pc 2.02~beta2-22+deb8u1 pn linux-doc-4.3 <none> Versions of packages linux-image-4.3.0-0.bpo.1-amd64 is related to: pn firmware-atheros <none> pn firmware-bnx2 <none> pn firmware-bnx2x <none> pn firmware-brcm80211 <none> pn firmware-intelwimax <none> pn firmware-ipw2x00 <none> pn firmware-ivtv <none> pn firmware-iwlwifi <none> pn firmware-libertas <none> pn firmware-linux <none> pn firmware-linux-nonfree <none> pn firmware-myricom <none> pn firmware-netxen <none> pn firmware-qlogic <none> pn firmware-ralink <none> pn firmware-realtek <none> ii xen-hypervisor-4.4-amd64 [xen-hypervisor] 4.4.1-9+deb8u3 -- debconf information: linux-image-4.3.0-0.bpo.1-amd64/postinst/depmod-error-initrd-4.3.0-0.bpo.1-amd64: false linux-image-4.3.0-0.bpo.1-amd64/postinst/mips-initrd-4.3.0-0.bpo.1-amd64: linux-image-4.3.0-0.bpo.1-amd64/prerm/removing-running-kernel-4.3.0-0.bpo.1-amd64: true
