Hello, |
| 2 |
|
| 3 |
Currently I'm using hotswap of the UltraBay devices (hdd and cd/dvd) on my IBM |
| 4 |
T43, kernel 2.6.23-gentoo-r3, the hdd is Ultra ATA 160GB. Hotswap of these works |
| 5 |
well. |
| 6 |
|
| 7 |
And now my problem: I've bought new UltraBay box with new hdd - SATA II 320GB. |
| 8 |
After hotswaping the new hdd (320), it is not detected, hdd led looks like the |
| 9 |
disk is under full load and the dmesg gives me: |
| 10 |
***** |
| 11 |

Yes, I'm patient but it's not recognized even after 30 minutes ... only the |
| 37 |
hotswap doesn't work, the rest of the system works well. |
| 38 |
|
| 39 |
When I start the system with plugged new disk (320), it works fine ... the disk |
| 40 |
is detected correctly, device in the /dev is created during the boot and the |
| 41 |
disk can be mounted and behaves well. Unplugging the disk works too, but |
| 42 |
plugging it back not :-( |
| 43 |
|
| 44 |
I've tried to compile newer kernels (2.6.25-gentoo-r7 and 2.6.25-gentoo-r8), but |
| 45 |
in these kernels the hotswap freezes the system like this: |
| 46 |
- plug/unpluf the cd/dvd works |
| 47 |
- plug old hdd (160) works |
| 48 |
- unplug old hdd (160) freezes the system (the system has to be started with hdd |
| 49 |
plugged in) |
| 50 |
- plug the new hdd (320) doesn't work |
| 51 |
- unplug new hdd (320) freezes the system (the system has to be started with hdd |
| 52 |
plugged in) |
| 53 |
|
| 54 |
If the system freeze there are not error messages in the /var/log/messages file, |
| 55 |
so I have no idea what's wrong :-( |
| 56 |
|
| 57 |
Can someone help? For me is not important if I use 2.6.23-gentoo-r3 kernel or |
| 58 |
newer one, but I want to be able hotswap the devices. |
| 59 |
|
| 60 |
Thanks a lot for help. |
