Hi, Following a suggestion from a misc member after I complained about slow IO on a IBM xSeries 336 (see 'write cache on scsi'), I tried to install a snapshot.
Except for the very slow filesystems creation, the install process went through ok. But when I tried to boot the newly installed machine, I got a kernel trap and was sent to ddb> bios: IBM eServer xSeries 336 -[883721U]- acpi0 at bios0: rev 0 acpi0: tables DSDT FACP APIC MCFG acpi0: wakeup device PCI0(S5) acpitimer0 at acpi0: 3579545 Hz, 24bits acpiprt0 at acpi0uvm_fault(0xd07ca0c0, 0xd1977000, 0, 3) -> 3 kernel: paga fault trap code=0 Stopped at bcopy+0x1a: repe movsl (%esi),%es:(%edi) bcopy(d1972684,73,d1973910,ac) at bcopy+0x1a aml_parseop(d1972684,d1973910,74) at aml_parseop+0xe6 aml_parseterm(d1972684,d092c8d0,390,d07a41d0,d1972684) at aml_parseterm+0x2c aml_callmethod(d1972684,d092c8d0,d198295f,d1965984,d077fb42) at aml_callmethod+0x26 aml_evalmethod(0,d1965984,0,0,d092c8d0) at aml_evalmethod+0x41 aml_evalnode(d1960e00,d1965984,0,0,d092c8d0,d092c8d0,d092c8e8,d0673662) at aml_evalnode+0xc7 acpiprit_getpcipus(d19726c0,d1965604,d092c958,d0673662,d1965384) at acpiprt_getpcibus+0x30 acpiprit_getpcipus(d19726c0,d1965484,64,d1955ef0,d092ca6c) at acpiprt_getpcibus+0xcf acpiprit_getpcipus(d19726c0,d1971d04,d092ca58,d1955f00,0) at acpiprt_getpcibus+0xcf acpiprit_attach(d1960e00,d19726c0,d092cae0,d1960e00,d1960e00) at acpiprt_attach+0x22 I did try to save theses messages in the dmesg and copy and paste them afterwords but I did not manage, I this was all written down and then typed in here.

But then again, I did not solve my original problem. A simple command like 'mv src.tar.gz ..' takes more than 10 seconds to execute.
