Ubuntu 10.04 - JMicron JMB363 SATA controller - kernel freeze

Hi Andrea,
Did you get any further on your problem after updating the disk firmware?

I experience exactly the same problem when i try to make a RAID1 with two Samsung HD204UI drives.
I'm using Fedora 14 (after first using Centos 5,6), i've updated the firmware although i've purchased the drives last week and i read somewhere that samsung is using the new firmware in the disk produced after dec. 2010.

I've got a mini itx board (Jetway jnc96fl) which has 4 sata ports, 2 with the intel chipset en two on the jmb363.
When i make a mirror with the intel ports there's no problem. Only with teh ports on the jmb363. Because i've bought this board to build a nas server with 4 2TB drives in Raid5 i hope there will be a solution. otherwise the board is useless :-(

Also good to mention is, that before i got the smasung drives i did some testing with 4 500GB WD drives, and was working ok.
So it seems to be a problem with the combination of the HD204UI's and the jmb363.

Well i hope you have found something in the mean time.

kind regards.

Hi Breekie,

I'm sorry to disappoint you. Unfortunately I haven't found any solution yet and, upgrading the HDs firmware, did not change anything.

I have temporarily bypassed the problem not using the jmb363 controller but an "IDE to SATA" converter which is not giving me any problem at all. Obviously it's a very poor solution but it does the job for now.

My hope is that, with the next Ubuntu/kernel upgrade, the jmb363 will be better supported... (fingers crossed)

Regards,
Andrea

Hi,

I tried the latest fedora 15 live cd, but no solution.
i'm afraid i Will have to look for another way to make a nasserver.

Regards

Like I said before the only way to solve it is to disable the jmicron controller. That's the only way that works for me. That's why I stay away from jmicron.

Yeah well... you can disable the jMicron controller if you have enough SATA ports to do what you wanna do.

In Breekie's case and mine we want to have a RAID5 and, if we disable the jMicron controller, we would end up with 2 SATA ports only... which are definitely not enough. That's why a workaround is needed... :-/

Maybe a SATA card or something.

^andrea^ · 06-27-2011, 02:46 PM

Yes. You are right...

In fact what I'm looking for is a PCI-E x1 with 2 or better 4 SATA ports...
The 2 port one is quite cheap. Even less than £10 in England. The 4 port one starts from £40/50...
I will try one of them... sooner or later.

This controller has quite a reputation. Hopefully one of the following links is helpful

Thanks for the links but i already searched (and found these threads)

The controller is on a mini itx (jetway jnc96fl) i wanted to create a nas with 4 sata disks in raid5.
There's only one pci slot on this board. External sata controllers with 4ports are mostly pci-e, so this is no option either.
I think my project with this board will end here :-(
