Subject: ALSA hang on 4.13.0-rc7
Date: Wed, 30 Aug 2017 12:03:34 +0200 [thread overview]
Message-ID: <20170830100334.GA281@x4> (raw)
On my system ALSA sometimes hangs:
sysrq: SysRq : Show Blocked State
task PC stack pid father
output:ALSA def D 0 171 1 0x00000000
Call Trace:
? __schedule+0x17c/0x720
? schedule_preempt_disabled+0x2d/0x80
? __mutex_lock_slowpath+0x141/0x420
? snd_pcm_common_ioctl1+0x2f/0x1400

? SyS_ioctl+0xa7/0x860
? task_work_run+0x70/0xa0
? entry_SYSCALL_64_fastpath+0x13/0x94
Only a reboot will fix the issue.
