Hi, For over a year now, I've been hot-swapping devices from the modular bay in my Omnibook by ensuring that any filesystem is umounted first (bad things happen if you forget this, duh!), doing an 'atacontrol detach 1', plugging in the new device and re-attaching the ATA channel. It's been working flawlessly, (and a very useful facility it is too). I recently updated to -STABLE from Mar 12, and this no longer seems to work 100%. I sometimes get away with detaching the CD-ROM, but the whole system is very likely to lock hard (with or without the drive LED on solid) either immediately or within 5-10 seconds after popping the modular device out. Detaching the secondary HDD is very much less likely to work, I think it's worked once or twice for about 15-20 failures. I /think/ I can increase my chances of getting away with it by waiting for a couple of minutes before ejecting - but this never used to be an issue. Has anything changed recently that might have an impact on this? TIA, AS -------------- next part -------------- A non-text attachment was scrubbed...
