 |
|
Hi all,
I've just done a fresh amd64 install, kernel 2.6.25-gentoo-r7, and I'm having problems with hotswap.
Although the sata_nv driver is supposed to support hotplug, it is not working. When I remove a disk, I can see in dmesg output the SATA link down. It finishes with this:
| Code: |
ata2.00: detaching (SCSI 1:0:0:0)
sd 1:0:0:0: [sdb] Synchronizing SCSI cache
sd 1:0:0:0: [sdb] Result: hostbyte=0x04 driverbyte=0x00
sd 1:0:0:0: [sdb] Stopping disk
sd 1:0:0:0: [sdb] START_STOP FAILED
sd 1:0:0:0: [sdb] Result: hostbyte=0x04 driverbyte=0x00
|
However, when I reattach the disk (no matter which port, I have three available) it gets never recognized, I have to restart the system.
Do you have any clue of what could it be? I have hotplug compiled into the kernel, even PCI and PCI Express hotplug, I think that has nothing to do though.
Thanks in advance! |

hi all!
i have the same chipset and have the same question like m.a. i'd like to give away my 3ware raid controller cause i got problems all time so i would like to setup software raid5 with having the ability to hotswap drives. id like to use ahci mode which is suppoed to support hotswap...
EDIT: after some search i found out that the mcp55 does not support hotswap, only newer chipsets do (they use the ahci driver which supports hotswqap).
thx
