Package: iceweasel Version: 38.3.0esr-1 Severity: important --- Please enter the report below this line. --- Note: Happens most often during Iceweasel session or soonthere after or trying to close Iceweasel. Bug may be elsewhere, i.e. in KDE compositing/rendering but do not know where to place. Has also occurred switching between concurrent KDE sessions (but after using iceweasel). So please move to where it better belongs.
Too often, running iceweasel or closing it, will get errors shown in dmesg: [ 304.950737] nouveau E[ PFIFO][0000:01:00.0] CACHE_ERROR - ch 16 [dolphin[3571]] subc 4 mthd 0x0000 data 0xbeef5201 [ 304.950825] nouveau E[ PFIFO][0000:01:00.0] CACHE_ERROR - ch 16 [dolphin[3571]] subc 4 mthd 0x0180 data 0xbeef0301 [ 304.950912] nouveau E[ PFIFO][0000:01:00.0] CACHE_ERROR - ch 16 * * * Rarely, I can get out and keep going.
