The device ID string is: TS64GSSD25-M, serial 002328450083, revision V0826
The south bridge is VIA VT82C586B
The lockup happens on partition scan, sometimes the scan passes and it
locks up when loading init. It doesn't get further.
The lockup is not dependent on IDE driver. I experienced it with Linux 2.6
IDE, Linux 2.6 LIBATA, Daniela's OS/2 DANIS506 driver (Daniela, if you
maintain a blacklist, you can add it there too) - switching to MWDMA
helped. Linux 2.2 locked up too (it doesn't set transfer mode and relies
on BIOS) and disabling UDMA in BIOS cured the problem.
I tried to switch to UDMA 0 and UDMA 1, but the lockups didn't go away,
they just became less frequent. With MWDMA 2 it works reliably.
I tested it in a motherboard with VIA133 IDE and it works there. I think
it also worked with that VT6421 card, but I can't test it now because I
moved root to that Transcend SSD and it wouldn't boot of that.
This is the list of PCI devices for the detailed information (note that
onboard IDE locks-up, not that additional VT6421 controller on a PCI
card).
