Hello,
Currently I'm using hotswap of the UltraBay devices (hdd and cd/dvd) on my IBM
T43, kernel 2.6.23-gentoo-r3, the hdd is Ultra ATA 160GB. Hotswap of these works
well.
And now my problem: I've bought new UltraBay box with new hdd - SATA II 320GB.
After hotswaping the new hdd (320), it is not detected, hdd led looks like the
disk is under full load and the dmesg gives me:
*****

Yes, I'm patient but it's not recognized even after 30 minutes ... only the
hotswap doesn't work, the rest of the system works well.
When I start the system with plugged new disk (320), it works fine ... the disk
is detected correctly, device in the /dev is created during the boot and the
disk can be mounted and behaves well. Unplugging the disk works too, but
plugging it back not :-(
I've tried to compile newer kernels (2.6.25-gentoo-r7 and 2.6.25-gentoo-r8), but
in these kernels the hotswap freezes the system like this:
- plug/unpluf the cd/dvd works
- plug old hdd (160) works
- unplug old hdd (160) freezes the system (the system has to be started with hdd
plugged in)
- plug the new hdd (320) doesn't work
- unplug new hdd (320) freezes the system (the system has to be started with hdd
plugged in)
If the system freeze there are not error messages in the /var/log/messages file,
so I have no idea what's wrong :-(
Can someone help? For me is not important if I use 2.6.23-gentoo-r3 kernel or
newer one, but I want to be able hotswap the devices.
Thanks a lot for help.
Pat
