2.6.14-mm1 libata pata_via

[Chris Boot <bootc@bootc.net>]

Hi all,

Since I've only got a DVD drive on good ol' PATA, I thought I'd try  
Alan's latest VIA PATA driver for libata, to see where I got. Well,  
the machine simply doesn't boot, preferring to get stuck after  
detecting the drive. I've tried with and without  
libata.atapi_enabled=1 and get the same result in both cases. Here's  
my log with some SysRq output that might be useful:

I've got CONFIG_IDE=n and CONFIG_SCSI_PATA_VIA=y. ata1 and ata2 are  
two other Seagate HDDs on a sata_sil controller. I can provide a full  
dmesg and other details should they be required!

HTH,
Chris
