Hi Dave, While finishing my work on the makedumpfile --dump-dmesg fix for kernels higher than 3.5, I may have found a minor bug in your 'log -m' command. I was trying to compare my output from makedumpfile --dump-dmesg with your log -m output. Or else I misunderstood your 'dump_log_entry' command and how the message log level should look. When running in -d1 on an F18 kernel, I get the following : > crash> log -m | tail > log 45368dc -> msg: 45368ec ts_nsec: 83443019994 level: 21026 text_len: 54 dict_len: 0 > [ 83.443019] <21026>RIP [<ffffffff81393986>] sysrq_handle_crash+0x16/0x20 > > log 4536924 -> msg: 4536934 ts_nsec: 83443019994 level: 8322 text_len: 23 dict_len: 0 > [ 83.443019] <8322> RSP <ffff8800363dde38> > > log 453694c -> msg: 453695c ts_nsec: 83443019994 level: 17286 text_len: 21 dict_len: 0 > [ 83.443019] <17286>CR2: 0000000000000000 The message log level in brackets that is displayed seems dubious to me. Since I didn't have access to the log.level offset in the vmcoreinfo, I had to hack and hard code the structure offset in makedumpfile. While doing that, I used a 3 bit mask to get the level:3 element but it looks like what you report is the full log.level value. So I ported back what I had done in makedumpfile in your dump_log_entry (patch attached) and tested on crash 6.1.2. I got : > crash> log -m | tail > log 458df8c -> msg: 458df9c ts_nsec: 83443019994 flags/level: 22 text_len: 54 dict_len: 0 > [ 83.443019] <2>RIP [<ffffffff81393986>] sysrq_handle_crash+0x16/0x20 > > log 458dfd4 -> msg: 458dfe4 ts_nsec: 83443019994 flags/level: 82 text_len: 23 dict_len: 0 > [ 83.443019] <2> RSP <ffff8800363dde38> > > log 458dffc -> msg: 458e00c ts_nsec: 83443019994 flags/level: 86 text_len: 21 dict_len: 0 > [ 83.443019] <6>CR2: 0000000000000000 Does the message log level looks correct to you with that modification ?
