Description Michael A. McLean 2001-09-24 18:28:31 UTC
* re0924.0-ia64 * ia64 / German / NFS / Full Server / post-install: USB .... Upon fresh insertion of a USB device (I've seen it with a floppy, zip and even a mouse) updfstab begins consuming nearly all available cpu time. Here is a ps capture showing 99% usage: F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 000 R 0 1540 1512 99 76 0 - 290 invoke ? 2:45 /usr/sbin/u For the floppy and zip drives, mounting causes updfstab to exit. Umounting later does not cause another cpu drain. Even reinsertion of the same device does not cause the drain.
Comment 1 Bill Nottingham 2001-09-26 21:53:59 UTC
Does this happen on all ia64 server machines, or just one particular one? I can't reproduce this on a workstation machine.
Comment 2 Bill Nottingham 2001-09-26 21:54:18 UTC
(at least not with a USB keyboard)
Comment 3 Michael A. McLean 2001-09-26 22:18:25 UTC
A USB keyboard has never caused the problem, only drives (and a mouse once or twice, but that is erratic). I've seen it on 3 of the itaniums.
Comment 4 Bill Nottingham 2001-09-27 01:12:24 UTC
All server boxes, though, yes? In any case, could you drop one of the drives off by my desk? I'll try and reproduce it there (easier to debug...)
Comment 5 Bill Nottingham 2001-09-27 19:08:11 UTC
This *should* be fixed with kernel-2.4.9-0.13.
