Description of problem: After reading a CD which contained bad data kernel crashed when trying to unload scsi-mod module. This happened after I was trying to read a CD written on Windows XP. Version-Release number of selected component (if applicable): kernel-2.6.10-1.741_FC3 How reproducible: Always Steps to Reproduce: 1. download attached foo.toc 2. dd of=foo.bin bs=150k count=0 seek=10 3. insert a blank CD-RW into USB CD writer 4. cdrdao write --device 0,0,0 --buffers 10 foo.toc 5. wait for cdrdao to finish with error 6. cdrdao read-cd --device 0,0,0 --datafile xxx.bin xxx.toc 7. wait for cdrdao to finish with read errors 8. turn off CD writer 9. modprobe -r sr-mod usb-storage Actual results: Kernel oops Expected results: It should unload specified modules Additional info: I've tried my best to reproduce that broken CD, but with the real CD kernel oopsed with different diagnostics just after I've turned off the writer's power. That looks very similar to recently fixed bug with pulling off USB writer's cable. Created attachment 109921 [details]

dmesg output
It is the same with kernel-2.6.12-1.1398_FC4 Mass update to all FC4 bugs: An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks. fixed in kernel-2.6.13-1.1532_FC4 |
