[Moved from -stable to -scsi, as that seems to be where the problem is.] Jamil Taylor <jamil_taylor@pobox.com> types: > I attempted this one more time and got it to work.

Having updated today - or rather tried to - I'm now seeing similar problems. Keyboard input is obviously active, and the console driver will let me switch virtual ttys, but no user processes seem to be getting any cpu. There's no tape drive involved in freezing the system, just disk activity across multiple devices on the controller. In particular, I've got: <SEAGATE ST39236LW 0004> at scbus0 target 0 lun 0 (pass0,da0) <SEAGATE ST39173W 5958> at scbus0 target 1 lun 0 (pass1,da1) attached to: <Adaptec aic7890/91 Ultra2 SCSI adapter> port 0xe800-0xe8ff mem 0xfebff000-0xfebfffff irq 10 at device 14.0 on pci0 I can get it to freeze reliably - meaning every time I tried to start X - on a kernel supped earlier today, wherease the one from June 24th has no problems. I've got a debugging kernel built, but don't know if I'll have time to do any work on this in the next two weeks. I should be dealing with email, though. James, you might report your hardware configuration as well. <mike > -----Original Message----- > From: owner-freebsd-stable@FreeBSD.ORG > [mailto:owner-freebsd-stable@FreeBSD.ORG]On Behalf Of Jamil Taylor > Sent: Saturday, June 30, 2001 1:43 PM > To: stable@FreeBSD.ORG > Subject: System Hang During tar Backup > > > I am encountering a problem when using tar to backup the files on my system. > I am uncertain of when this problem began, but this worked a month ago.
