Re: Severe clock problems with OpenBSD VM on OpenBSD Host

Same here, and none of the tricks I was finding worked. I was also
unsatisfied with the idea of running rdate or restarting ntpd often
enough to keep things in sync. Making use of the vmmci(4) timedelta
sensor, I found and modified a piece of existing code by Ted U. to
work around this problem until someone far smarter than I figures out
a proper solution.
Attached, but linked as well in case the attachment doesn't make it.

Neither perfect nor desirable, but workable! It makes a lot of
adjustments and has been doing an ok job so far. Doesn't seem to
perfectly keep the clock in a synced state according to "ntpctl -sa".
Here's what it looks like running, and these are the sorts of deltas
it regularly sees and applies.

Re: CF Card on Sparc 64
Duncan, http://wtf.hijacked.us/wiki/index.php/Sun_Netra_t1_compact_flash_root I've done this before; I don't have it running anymore, but it worked really well. Don't know if this helps, but I thought I'd offer it to the archives for those interested. The meat of it is finding the right alias for openboot.

Keyboard interrupt problem ('lag')
Hello all; I asked a while back about a 'lag' in keyboard response on my laptop (Gateway MT3705) that runs -current. Someone responded off-list and noted that it was an interrupt issue. I was wondering if there is any known workaround / fix for it; the machine can be very hard to use for day to day operation with this happening. Looking through the dmesg, it doesn't look like an irq sharing problem necessarily? I'm currently working on building a new -current and a new xenocara to test with since this one is a little dated. dmesg is as follows: OpenBSD 4.1-current (EXTRO.acpi-mp) #1: Tue Apr 17 09:34:02 EDT 2007 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/EXTRO.acpi-mp cpu0: Genuine Intel(R) CPU T2060 @ 1.60GHz (GenuineIntel 686-class) 1.60 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,EST,TM2,xTPR real mem = 1004621824 (981076K) avail mem = 910696448 (889352K) using 4278 buffers containing 50356224 bytes (49176K) of memory mainbus0 (root) bios0 at mainbus0: AT/286+ BIOS, date 12/07/06, BIOS32 rev. 0 @ 0xfd5fd, SMBIOS rev. 2.4 @ 0xdc010 (41 entries) bios0: Gateway MT3705 pcibios0 at bios0: rev 2.1 @ 0xfd580/0xa80 pcibios0: PCI IRQ Routing Table rev 1.0 @ 0xfde90/336 (19 entries) pcibios0: no compatible PCI ICU found: ICU vendor 0x1002 product 0x4372 pcibios0: Warning, unable to fix up PCI interrupt routing pcibios0: PCI bus #8 is the last bus bios0: ROM list: 0xc/0xd000 0xdc000/0x4000! acpi0 at mainbus0: rev 0 acpi0: tables DSDT FACP SLIC APIC MCFG SSDT acpitimer0 at acpi0: 3579545 Hz, 32 bits acpi device at acpi0 from table DSDT not configured acpi device at acpi0 from table FACP not configured acpi device at acpi0 from table SLIC not configured acpimadt0 at acpi0 table APIC addr 0xfee0: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: apic clock running at 133 MHz cpu1 at mainbus0: apid 1 (application processor) cpu1: Genuine Intel(R) CPU T2060 @ 1.60GHz (GenuineIntel 686-class) 1.60 GHz cpu1: FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH,DS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,SBF,SSE3,MWAIT,EST,TM2,xTPR ioapic0 at mainbus0: apid 2 pa 0xfec0, version 21, 24 pins acpi device at acpi0 from table MCFG not configured acpi device at acpi0 from table SSDT not configured acpiprt0 at acpi0: bus 0 (PCI0) acpiprt1 at acpi0: bus 0 (PB2_) acpiprt2 at acpi0: bus 0 (PB3_) acpiprt3 at acpi0: bus 2 (PB4_) acpiprt4 at acpi0: bus 5 (PB5_) acpiprt5 at acpi0: bus 0 (PB6_) acpiprt6 at acpi0: bus 0 (PB7_) acpiprt7 at acpi0: bus 8 (P2P_) acpiprt8 at acpi0: bus 1 (AGP_) acpiec0 at acpi0: EC__ acpicpu0 at acpi0: CPU0: acpicpu0: C3 not supported acpicpu1 at acpi0: CPU1: acpicpu1: C3 not supported acpitz0 at acpi0, critical temperature: 100 degC acpiac0 at acpi0: AC unit offline acpibat0 at acpi0: BAT0: model: 6MSB serial: type: Li oem: SMP-P acpibtn0 at acpi0: PWRB acpibtn1 at acpi0: LID0 acpibtn2 at acpi0: SLPB vesabios0 at mainbus0: version 2.0, ATI Technologies Inc.

Hello all,
This has been driving me nuts for weeks (ever since upgrading to -current):
I type at a fairly fast rate with very high accuracy and on this laptop it
all goes downhill in a handbasket; makes it very hard to use regularly.
It seems to be aggravated by typing over an SSH connection, but is still
very apparent at a local console or in an xterm/aterm/etc.
Many characters are missed, sometimes end up in the wrong order with an
obvious lag/delay, etc. I've tried playing with wsconsctl tunables like
keyboard.repeat.del{n,1} without any real results.
If anyone has any idea, I'd be very interested to hear it!
Great work on the 4.1 branch and xenocara!
(Finally get 1280x800 resolution in X.org, but still have a few issues)
In fact, now -current lacks only a native working RTL8185 and azalia driver
and this laptop is perfect; thanks everyone.
