I've just found that my VMware Workstation virtual machine doesn't boot as expected with recent 6.0-CURRENT kernel. For example, with 6.0-CURRENT-20040912-JPSNAP boot floppies, following three lines are the last message, and stops VM forever: md0: Preloaded image </mfsroot> 4423680 bytes at 0xc0a33764 acpi_cpu: throttling enabled, 8 steps (100% to 12.5%), currently 100.0% pid 24: corrected slot count (0->1) I've tried to boot with the floppies "boot -v", and got: ata0: reiniting channel .. ata0: reset tp1 mask=03 ostat0=50 ostat1=50 ata0-master: stat=0x50 err=0x01 lsb=0x00 msb=0x00 ata0-slave: stat=0x50 err=0x01 lsb=0x00 msb=0x00 ata0: reset tp2 stat0=50 stat1=50 devices=0x3<ATA_SLAVE,ATA_MASTER> ata0: resetting done .. pid 24: corrected slot count (0->1) ata0: reiniting channel .. ata0: reset tp1 mask=03 ostat0=50 ostat1=50 (... and stops) After some try-and-error challenge, it seems that this occurs if PREEMPTION kernel option is enabled (note that SCHD_4BSD is used). In anyway, anybody have experienced this problem? I'm afraid that next 5.3 beta (it'll be 5.3-BETA4) have the same problem. -- - Makoto `MAR' Matsushita
