This was a bug in cdrecord which used generic scsi access to lock the drive. The kernel cannot notice this. AFAIK this bug is fixed in cdrecord.

One sane way to do this is to store the sig on a ro medium and make the kernel check the sig of every binary before it is run. HOWEVER, this means no compilers will work, and you have to delete all script languages like perl or python (or make all of them check the signature).

oops with 2.4.5-ac12
I got the following oops with 2.4.5-ac12 after I issued "rmmod -a" twice. I only notices the oops after I issued "rmmod -a" once which might explan that ksymoops cannot name the module which caused the oops. This is possibly ALSA-related (although I never had problems with unloading alsa modules befode). Walter WARNING: This version of ksymoops is obsolete. WARNING: The current version can be obtained from ftp://ftp.ocs.com.au/pub/ksymoops Options used: -V (default) -o /lib/modules/2.4.5-ac12/ (default) -k /proc/ksyms (default) -l /proc/modules (default) -m /usr/src/linux/System.map (default) -c 1 (default) You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.

Re: Linux 2.4.5-ac15
I had already two crashes with ac15. The system was still ping-able, but login over the network didn't work anymore. The first crash happened after I started xosview and noticed that the system almost used up the swap (for no apparent reason). The second crash happened shortly after I started fsck on a crypto-loop device. This does not happen with ac14, even under heavy load. I noticed a second problem: Sometimes the system hangs completely for approximately ten seconds, but continues just fine after that. I have seen this with ac14 and ac15, but not with ac12. This is a mixed IDE/SCSI (Adaptec) system, 128MB RAM/256MB swap on a Gigabyte 440LX mainboard with a Pentium II.

Taken with ac14, vmstat 1 was started (long) before the hang and interrupted about five seconds after it.

Hi Rik, I tried 2.4.6-pre5 with your patch (quoted at the end). Oberservations: I still see this hang, it seemed to last longer than with ac14/ac15 (say, 30 seconds). There was no heavy swapping going on, eiter before or after the hang. During the hang there was no disc activity. Compared with 2.4.5ac I saw that 2.4.6-pre5 uses much less swap (according to xosview). With the load I tried (many open browser windows) the ac series used to use 80-100MB of swap; 2.4.6-pre5 only used 40MB swap for roughly the same number of windows open. I forgot to press SysRq-T to get a trace, I'm afraid. kdb didn't compile with this kernel either (although patching worked). I had vmstat running in another window and stopped it a couple of seconds after the hang, here are the last line of its output: procs memoryswap io system cpu r b w swpd free buff cache si sobibo incs us sy id 2 0 0 36424 3232888 45036 0 0 4 0 255 3250 56 13 32 1 0 0 36424 3096888 45048 0 012 0 140 1010 37 6 58 4 0 0 36424 2964888 45060 0 012 0 228 1304 90 6 4 3 0 0 36424 3052900 44668 0 088 0 259 2522 88 12 0 2 0 0 36424 3164900 44524 0 0 4 0 144 3556 87 13 0 3 0 0 36424 2812900 44468 0 0 8 0 211 2007 87 11 3 5 0 0 36424 2812912 44108 0 020 0 196 1243 92 8 0 4 0 0 36424 2812920 43836 0 0 108 0 271 2928 88 12 0 4 0 0 36424 2808920 42728 0 0 228 0 284 2042 85 11 5 2 0 0 36424 3112924 42416 76 5004 288 5260 385 948 84 11 6 4 0 0 36424 2816940 42016 0 0 100 0 223 1252 94 3 3 3 0 0 36424 2812944 41472 0 0 0 0 229 1392 92 8 0 3 0 0 36424 2812948 41112 0 068 0 264 1107 95 3 2 1 0 0 36424 2932948 40756 0 0 0 0 262 879 92 8 0 2 0 0 36424 2808952 40740 0 0 0 0 191 2244 36 12 53 4 0 0 36424 2808952 40504 32 032 0 242 975 93 6 2 2 0 0 36424 3252956 40008 0 064 0 249 2505 85 15 0 3 0 0 36424 2972956 39996 0 0 8 0 127 1419 88 10 2 3 0 0 36424 2988956 39108 0 020 0 247 1632 83 17 0 2 0 0 36424 3332964 38496 0 0 176 0 218 955 91 9 0 3 0 0 36424 3180964 38724 120 0 232 0 112 3026 89 11 0 procs memoryswap io system cpu r b w swpd free buff cache si sobibo incs us sy id 4 0 0 36424 3020968 38800 64 064 0 158 2008 87 13 1 3 0 0 36424 2808936 38192 0 0 192 552 232 678 90 6 4 2 0 0 36424 2988936 37632 0 0 0 4 167 678 98 2 0 2 0 0 36424 2868940 37592 0 0 4 104 177 1137 93 7 0 3 0 0 36396 2852940 37592 0 0 020 185 1125 93 7 0 4 0 0 36396 2848984 37624 0 06064 193 1245 92 8 0 5 0 0 36396 2244 1000 37656 0 028 176 161 2377 69 31 0 1 0 0 36396 2364 1004 37660 0 0 8 244 180 1836 75 25 0 1 0 1 36396 2484 1004 37780 100 0 104 248 178 2369 61 38 1 4 0 1 36384 2020 1012 38328 520 0 560 148 185 1696 58 19 22 6 0 0 45940 1744 1012 47676 108 724 368 868 6886 186930 1 99 0 2 0 1 45856 2528 1028 46480 272 5480 752 5524 264 2413 82 18 0 5 0 0 46072 2732 1028 45740 0 6636 8 6636 297 1165 84 16 0 4 0 0 46072 2532 1028 45776 0 020 4 245 3310 88 13 0 3 0 0 46072 2392 1040 45336 0 024 0 119 1296 91 9 0 2 0 0 46072 2832 1052 44872 0 048 4 113 1276 91 9 0 3 0 0 46072 2392 1056 44544 0 0 0 0 104 943 97 3 0 2 0 0 46068 2808 1056 44112 1104 0 1164 0 144 870 70 11 19 1 0 0 46052

Ok, I managed to press SysRq-T this time ond got a trace for my hang. Symbols are resolved by klog. If you prefer ksymopps please tell me, I used klog because ksymopps seems to drop all lines without symbols. There seem to be no kernel deamons in the trace? Is this normal, or is the log buffer too small? If it is the latter, how can I increase its size? Kernel was 2.4.6pre5 plus Rik's patch (at the end). I see the same hangs with the ac series.
