| |
I've encountered a loopback bug on kernel-2.4.3+international_patch. I haven't been able to pin down what the bug is exactly, but these are the conditions under which it manifests:
1. connect file to loopback device 2. build fs on loopback device 3. mount fs and use it 4. read the file 5. lockup, about 1 out 5 times.
The lockup occurs randomly and seems to have random effects. Sometimes user-space scheduling is lost and sometimes there is a total lockup. This is all I could extract from /var/log/messages in several crashes:
