The following problem happened while doing an 'apt-get upgrade -u': The first run of apt-get upgrade crashed with a segmentation fault after downloading all the packages and while unpacking and setting them up. After the segfault I run the command again, the result was no output on the terminal and apt not returning, hitting CTRL-C did not cause the process to be killed. kill -9 did not kill the process either. I could not run apt-get form a different terminal because the process kept the package database locked. The STAT column of the ps command had a value of 'D', the TTY was '?', and the process was taking no cpu time. After a reboot, I found these lines in syslog: Apr 24 01:05:39 habbakuk kernel: Unable to handle kernel paging request at virtual address 0020010c Apr 24 01:05:39 habbakuk kernel: printing eip: Apr 24 01:05:39 habbakuk kernel: c0132631 Apr 24 01:05:39 habbakuk kernel: *pde = 00000000 Apr 24 01:05:39 habbakuk kernel: Oops: 0000 Apr 24 01:05:39 habbakuk kernel: CPU: 0 Apr 24 01:05:40 habbakuk kernel: EIP: 0010:[vfs_rename_other+389/736] Not tainted Apr 24 01:05:40 habbakuk kernel: EFLAGS: 00010246 Apr 24 01:05:40 habbakuk kernel: eax: 00200000 ebx: c0d989a0 ecx: 00200000 edx: c0b3f740 Apr 24 01:05:40 habbakuk kernel: esi: c0b3f740 edi: c0d989a0 ebp: c0d989a0 esp: c1839f28 Apr 24 01:05:40 habbakuk kernel: ds: 0018 es: 0018 ss: 0018 Apr 24 01:05:40 habbakuk kernel: Process dpkg (pid: 5048, stackpage=c1839000) Apr 24 01:05:40 habbakuk kernel: Stack: c0d989a0 c0b3f740 c0d989a0 c1f69dc0 c01327c9 c0d989a0 c0b3f840 c0d989a0 Apr 24 01:05:40 habbakuk kernel: c0b3f740 c0b3f840 c0b3f740 c0b3f740 c01329a6 c0d989a0 c0b3f840 c0d989a0 Apr 24 01:05:40 habbakuk kernel: c0b3f740 c1838000 bffff934 bffff8d0 bffff46c c1f69dc0 c0e33000 c1aa0000 Apr 24 01:05:40 habbakuk kernel: Call Trace: [vfs_rename+61/136] [sys_rename+402/544] [system_call+51/64] Apr 24 01:05:40 habbakuk kernel: Apr 24 01:05:40 habbakuk kernel: Code: f6 80 0c 01 00 00 18 74 0a ba ff ff ff ff e9 17 01 00 00 66 The kernel is a 2.4.18, compiled from Debian sources.
