Hi Neel, I updated my STABLE to r281384M and applied the patch. It seems that the patch solved the issue: # pciconf -vl | grep ppt ppt0@pci0:0:20:0: class=0x0c0330 card=0x8c311849 chip=0x8c318086 rev=0x05 hdr=0x00 ppt1@pci0:0:26:0: class=0x0c0320 card=0x8c2d1849 chip=0x8c2d8086 rev=0x05 hdr=0x00 ppt2@pci0:1:0:0: class=0x010601 card=0x91721849 chip=0x91721b4b rev=0x11 hdr=0x00 As I'm not a developer, please tell me whether this patch will be added to STABLE or if I need to patch again when I update the system in the future.
