Public bug reported: Hang occurs at the K3B splash screen, before the GUI displays.
Keyboard and mouse unresponsive including sysrq. Cannot provide any other hang information because the entire terminal is frozen on hang. Xclock freezes too so apparently the cpu halts, not just the interrupts. Sorry, I am not a sysadmin so I do not know which log files to send or how to include them with this report. I did do some reading on submitting bug reports but the hang is intermittent and I do know which logs to retrieve after a hang even if the system were responsive. I may update the report if I can find out anything more. Only hard reset or power cycle recovers. Would not trouble you except this problem terminates all jobs in process so it seemed important. I saw a similar K3B report somewhere but it was thought to be hardware- specific to a VIA chipset that had just been installed on a new disk controller card(?). My system probably does not have that hardware and I could not find that report again. Anyway it does not seem to be hardware specific since I also experienced this same problem. Intermittent problems can be difficult to duplicate and debug, but I thought you might want to know about it anyway. Good luck. Thank you for your hard work. Otherwise, the system is running beautifully. Thank you for Linux. Platform: Ubuntu 11.10 64-bit, Intel DG965WH main board (ICH8 chipset?, specs available from Intel) with Core 2 Duo E6400 2.13GHz, GEForce 7300GS driving 2 displays (HDTV 1080i via HDMI and SDTV via svideo), 8GB DRAM, Seagate SATA and Pioneer BD-DL running as slave on PATA with an inline SATA-PATA adapter plus an older NEC/SONY dvd PATA on master. (For some unknown reason, various Linux distributions - but not all - exhibit inconsistent behavior on this system and have difficulty mapping the PATA if I reverse the master and slave, with very odd behavior that prevents LiveCD boot and installation from CD. The drive order changes?? when the PATA boot drive is remapped?? after the kernel starts? I think maybe... but this is a different issue entirely (I hope) that does not affect the K3B problem I am reporting. PATA master/slave problems abound... I used to find them all the time when I did applications engineering for a drive controller manufacturer so I do not pay attention to them, I just avoid conflicting configurations whenever possible because master/slave problems are too ubiquitous to debug and mostly the disk controller interface on the hard disks is to blame which is why specific combinations of drives may or may not play together as master and slave or may work only in one configuration but not the other. In any case PATA is a dead technology now.) Boot drive 400GBx2 formatted mbr. Data drive 1.5TBx4 formatted GPT. Various RAID 0, RAID 1, RAID 5 volumes mounted. Full disk encryption on main data volumes (cryptsetup, not LUKS format). Mythtvfs mounted using mysql and fuse. Mythbackend running. System is intended for amusement of disabled person (formerly hardware engineer technical but not a programmer or sysadmin) so I may not be able to respond to inquiries in a timely fashion depending on health factors. In any case, there does not seem to be much information that can be developed without an execution trace and that is beyond my capabilities. Problem duplicated several times intermittently. Once it hung immediately after boot, before the encrypted file systems were opened. There was a burst of hangs and then it stopped so I am filing the report now on the expectation that some asynchronous factors affect the hang and it may or may not return. I did lose some data due to the first hang when a job terminated. I do not know how you will duplicate it if it is hardware specific, but on the off chance that it is not, I filed this report. If I could figure out how to update that other report I saw, I would have. Sorry, this is my first bug report.
