| |
Hallo,
I get a (repeatable) kernel panic in Linux 1.99.11 using the following commands:
mount /cdrom cd /cdrom grep -in ftam `find . -type f -print`
The CD-ROM is a Matsishita CD-ROM connected to a SoundBlaster16. Following is a part of the syslog messages:

I did an strace on the grep command, the last system calls (written down from the screen to paper):
mmap(0x400c2000,131072,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_FIXED,3,0x48000)=0x400c2000 mmap(0,335872,PROT_READ|PROT_WRITE,MAP_PRIVATE|0x20,4294967295,0)=0x400e3000 lseek(3,425984,SEEK_SET)=425984 --> crash
