Created attachment 210107 [details] 11.3-STABLE dmesg for SE7525GP2 Hi, Intel SE7525GP2 MB (quite old, I know) When using MINIMAL and trying to load atapci as module, atapci reports low speed for attached disks : ada4 at ata2 bus 0 scbus4 target 0 lun 0 ada4: <SanDisk SSD PLUS 120GB UE4500RL> ACS-2 ATA SATA 3.x device ada4: Serial Number 1841B1803114 ada4: 33.000MB/s transfers (UDMA2, PIO 512bytes) ada4: 114480MB (234455040 512 byte sectors) Kernel spits messages about interrupt storm on irq used by atapci. When ata support is compiled into kernel, the reported speed is fine : ada4 at ata2 bus 0 scbus4 target 0 lun 0 ada4: <SanDisk SSD PLUS 120GB UE4500RL> ACS-2 ATA SATA 3.x device ada4: Serial Number 1841B1803114 ada4: 150.000MB/s transfers (SATA 1.x, UDMA5, PIO 512bytes) ada4: 114480MB (234455040 512 byte sectors) I've reproduced the same issue using a freshly compiled 12.1-STABLE kernel Regards Éric Masson
