alpha: WARNING: CPU: 0 PID: 17 at kernel/softirq.c:150 __local_bh_enable_ip+0xbc/0x100
From: Meelis Roos
Date: Mon Oct 10 2016 - 02:51:17 EST
Revived my alphapc 164 and found that 4.6.0-rc6-00123-g21a9703 was
showing a warning on bootup. Tried 4.8.0, same warning.
Seems to be about SRM interrupt coming in at a bad time?
Full dmesg from 4.8.0:
