Title:
mountall 100% cpu ussage
Status in “mountall” package in Ubuntu:
New
Bug description:
After loging in to KDE I see 100% cpu ussage by mountall. I don't
konow the exact case, but I suspect AoE or loop devices. Also, it
doesn't happen on every boot and started several days ago. Previously
it ocasionaly used to freeze at boot. I'm not 100% sure those two
issues are related, however since the high cpu ussage started to come
out I never experienced boot freeze again.
