I'm using FreeBSD 2.2.8. If I write a file which is not a complete number of blocks to /dev/nrst0 (which in my case is an HP "C1554A DDS-3 SCSI DAT Drive", according to the printed documentation), the kernel seems to hang. No panic or other kernel messages. No response to keyboard (including Alt-F<n>), no response to ping. It seems irrelevant what I use to do the writes (certainly both cat and dd break it). I can work around using "dd conv=osync". Here's my SCSI driver initializing (from dmesg): aic0 at 0x340-0x35f irq 11 on isa aic0 waiting for scsi devices to settle (aic0:1:0): "IBM DCAS-34330 S65A" type 0 fixed SCSI 2 sd0(aic0:1:0): Direct-Access 4134MB (8467200 512 byte sectors) (aic0:2:0): "HP C1537A L708" type 1 removable SCSI 2 st0(aic0:2:0): Sequential-Access density code 0x25, variable blocks, write-enabled Nick Barnes Systems Manager Geodesic Systems To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
