Bug#816702: linux-image-4.3.0-0.bpo.1-amd64: soft lockups in raid10
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
