I recently upgraded to Raring (from 12.10) and am now seeing spotify freeze often. I unfortunately never use rhythmbox or flash, so I cannot verify if those have issues as well.
I see: 08:03:47.719 E [watchdog.cpp:179 ] Fatal deadlock detected - would have crashed!! (Thread: gui) in my console when this occurs. This message repeats every second; I came in this morning to a terminal that filled its entire scrollback buffer with messages like these. I attached gdb and tried to figure out what the threads were doing: (gdb) info thr Id Target Id Frame 23 Thread 0x7ffbc3009700 (LWP 10057) "Dns Thread" pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 22 Thread 0x7ffbc2f88700 (LWP 10058) "Network Thread" 0x00007ffbcce1a3cd in poll () at ../sysdeps/unix/syscall-template.S:81 21 Thread 0x7ffbc2f07700 (LWP 10059) 0x00007ffbcce1a3cd in poll () at ../sysdeps/unix/syscall-template.S:81 20 Thread 0x7ffbc2a49700 (LWP 10061) "BrowserDBThread" pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 19 Thread 0x7ffbc2248700 (LWP 10062) "SignalSender" sem_wait () at ../nptl/sysdeps/unix/sysv/linux/x86_64/sem_wait.S:85 18 Thread 0x7ffbbf7dc700 (LWP 10063) "NetworkChangeNo" syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:38 17 Thread 0x7ffbbefdb700 (LWP 10064) "inotify_reader" 0x00007ffbcce1f233 in select () at ../sysdeps/unix/syscall-template.S:81 16 Thread 0x7ffbbe7b9700 (LWP 10067) "Cef_FileThread" syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:38 15 Thread 0x7ffbbdfb8700 (LWP 10068) "Cef_IOThread" syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:38 14 Thread 0x7ffbbcd91700 (LWP 10069) "AppCacheDBThrea" pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 13 Thread 0x7ffbbc02b700 (LWP 10070) pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:238 12 Thread 0x7ffbbbf29700 (LWP 10072) "dispatcher" pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:238 11 Thread 0x7ffbbbea8700 (LWP 10073) "dispatcher" pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:238 10 Thread 0x7ffbbbe27700 (LWP 10074) "AsyncKeyValueSt" pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:238 9 Thread 0x7ffbb5745700 (LWP 10078) "threaded-ml" 0x00007ffbcce1a3cd in poll () at ../sysdeps/unix/syscall-template.S:81 8 Thread 0x7ffbb7a46700 (LWP 10079) "spotify" 0x00007ffbccdedd3d in nanosleep () at ../sysdeps/unix/syscall-template.S:81 7 Thread 0x7ffbb0f43700 (LWP 10081) "QThread" 0x00007ffbcce1a3cd in poll () at ../sysdeps/unix/syscall-template.S:81 6 Thread 0x7ffbafa8e700 (LWP 10087) "NSS SSL ThreadW" pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 5 Thread 0x7ffbae28b700 (LWP 10088) "BrowserBlocking" pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 4 Thread 0x7ffbada8a700 (LWP 10089) "BrowserBlocking" pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 3 Thread 0x7ffbaea8c700 (LWP 16251) "threaded-ml" 0x00007ffbcce1a3cd in poll () at ../sysdeps/unix/syscall-template.S:81 2 Thread 0x7ffba7a06700 (LWP 16252) "spotify" 0x00007ffbccdedd3d in nanosleep () at ../sysdeps/unix/syscall-template.S:81 * 1 Thread 0x7ffbd5988a00 (LWP 10055) "spotify" 0x00007ffbd55abc5d in write () at ../sysdeps/unix/syscall-template.S:81 but it is not clear which thread is the 'gui thread'. This might be a spotify issue, but it seems related.
