Comment 94 for bug 285392

Hi,

I can confirm this bug with:
00:11.0 SATA controller: ATI Technologies Inc SB700/SB800 SATA Controller [AHCI mode]
on a Gigabyte GA-MA78GM-S2H rev. 1.1 with
AMD Sempron(tm) Processor 3000+
2 Gigs of ram.
Seagate 1500 GB S-Ata HDD (ST31500341AS)

I get the "softreset failed" error messages during boot, but could install ubuntu using another mainboard.

Something not already mentioned:
The system doesn't work stable, it comes to freezes when heavy IO load accurs. For example downloading an ubuntu iso and copy files from an external drive to the internal parallel. The system freezes completely, the mouse doesn't move anymore. Sys Magic Req + S does nothing, but Sys Magic Req + B does reboot the machine instantly. Strg+Alt+F1 doesn't switch to a terminal anymore.
Another way to reproduce this error is deleting a lot of small files from the drive. If I rm -r somedir_With_a_lot_of_files/ the system will freeze after 1-2 seconds. Nothing responses and work anymore except the "B" Sys Magic Request (Alt+print+B).
It comes only to problems when IO load is caused by write requests, normal read operations (and a lof of them for example while indexing the harddrive) causes no problems. Also copying files with ssh causes no problems because of the slow processor the IO load is not very high.

Deactivating HPET, using all_generic_ide and switching to IDE mode (non-ahci) makes no difference.

I've also tried to delete the directory from a ubuntu live cd to be sure nothing causes the problem that I installed on the HDD. Same result. System freezes.

What is with the patch? Is it in the kernel now? In vanilla or ubuntu?
