Using a week-old CURRENT to read the disk with the bad sectors when it's hooked up to a SiL 3112 controller yields the following result: ... ad4: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=478486335 g_vfs_done():ad4s1d[READ(offset=244984971264, length=16384)]error = 5 ad4: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=478507071 g_vfs_done():ad4s1d[READ(offset=244995522560, length=131072)]error = 5 ata2: SATA connect ready time=1480ms ata2: sata_connect devices=0x1<ATA_MASTER> ata2: SATA connect ready time=10000ms ata2: sata_connect devices=0x0 ad4: FAILURE - device detached subdisk4: detached ad4: detached unknown: timeout waiting to issue command unknown: error issueing SETFEATURES SET TRANSFER MODE command unknown: req=0xc16e4000 SETFEATURES SET TRANSFER MODE semaphore timeout !!

The process reading the disk gets stuck in "getblk D+" status according to 'top' and cannot be killed. Compared to 5.4-RC4 this is a regression imho. /Daniel Eriksson
