The Storage Router Business Unit of Cisco Systems is also seeing this problem when running some of our storage test suites on both e.3 and e.10 enterprise kernels. For now, we've reduced the frequency of umounts in our test scripts in order to lessen the impact. I can provide additional kernel oops text if needed. We see the problem most often when a umount occurs while large amounts of filesystem I/O are occuring (to other devices). I haven't yet checked to see if unmounting multiple filesystems at the same time ie needed to trigger the bug. My test script doesn't specifically do that, but it doesn't avoid it either. I typically get an oops in under an hour. The machine is effectively useless after that. Larry, I assume this will be in AS2.1Q2 errata. Correct? Fixed in kernel-2.4.9-e.8 Larry Woodman I'm experiencing this problem in 7.2, 2.4.9-31. I can't tell from the bug listing what I do to fix it.
