Q: how to increase ACPI_MAX_TASKS
Hello, Could you please advice me how to increase ACPI_MAX_TASKS from 32 (default) to 64 or 128 ? (1) I am running FreeBSD 9.1-RELEASE-p6, which was updated via freebsd-update. # uname -srmv FreeBSD 9.1-RELEASE-p6 FreeBSD 9.1-RELEASE-p6 #0: Wed Aug 21 20:40:52 UTC 2013 r...@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 (2) Now, dmesg shows an error regarding AE_NO_MEMORY. # dmesg (snip) AcpiOsExecute: failed to enqueue task, consider increasing the debug.acpi.max_tasks tunable ACPI Error: Method parse/execution failed [\\_SB_.PCI0.HEC2.HSCI] (Node 0xfe001d208380), AE_NO_MEMORY (20110527/psparse-560) ACPI Error: Method parse/execution failed [\\_GPE._L06] (Node 0xfe001d20c6c0), AE_NO_MEMORY (20110527/psparse-560) ACPI Exception: AE_NO_MEMORY, while evaluating GPE method [_L06] (20110527/evgpe-606) AcpiOsExecute: failed to enqueue task, consider increasing the debug.acpi.max_tasks tunable (snip) If needed, I will show all dmesg output. please request. (3) This is because ACPI_MAX_TASKS is defined as 32 in /usr/src/sys/dev/acpica/acpivar.h = /* Default maximum number of tasks to enqueue. */ #ifndef ACPI_MAX_TASKS #define ACPI_MAX_TASKS 32 #endif = (4) When I rewrite it to 64, the error in dmesg disappeared. So far so good, but I have to re-compile the kernel in this case. If possible, I'd like to change ACPI_MAX_TASKS value by sysctl.conf or something like that. (5) /usr/src/sys/dev/acpica/Osd/OsdSchedule.c mentions debug.acpi.max_tasks. = /* * Allow the user to tune the maximum number of tasks we may enqueue. */ static int acpi_max_tasks = ACPI_MAX_TASKS; TUNABLE_INT(debug.acpi.max_tasks, acpi_max_tasks); = But, I cannot write this sysctl tunable. That is unknown oid. # sysctldebug.acpi.max_tasks sysctl: unknown oid 'debug.acpi.max_tasks' # sysctl -w debug.acpi.max_tasks=64 sysctl: unknown oid 'debug.acpi.max_tasks' (6) If I have to re-compile the GENERIC kernel, where should I define ACPI_MAX_TASKS ? /etc/make.conf? kernel configuration file? or acpivar.h ? Thank you very much!!

Re: panic after acpi suspend/resume 9.1, 9.2rc3

This problem may have existed for some time in the 9.x kernel.
I've had similar panics for a while, but not had time to look into
it. I did not have this problem on 8.x kernels on this laptop.
It never happens when the system is cold-booted. It only happens
after a suspend/resume cycle or two which is why I am posting to
freebsd-apci to start with...
The repeat-by goes something like this:
- boot system
- suspend system
- resume system
- use as normal (mix of email/firefox/sh nvi/openvpn)
- perhaps suspend/resume again
- keep using as normal
- system panics, seems often to be when using firefox

This is where the NULL pointer is. Frame 9 (listed below) is above this.
(kgdb) list *0x80ceddcd
0x80ceddcd is in pmap_enter (../../../amd64/amd64/pmap.c:3577).
3572if ((m-oflags VPO_UNMANAGED) == 0) {
3573newpte |= PG_MANAGED;
3574pv = get_pv_entry(pmap, lock);
3575pv-pv_va = va;
3576CHANGE_PV_LIST_LOCK_TO_PHYS(lock, pa);
3577TAILQ_INSERT_TAIL(m-md.pv_list, pv, pv_list);
3578if ((newpte PG_RW) != 0)
3579vm_page_aflag_set(m, PGA_WRITEABLE);
3580}
3581
So it seems like pv_list of a page might be busted? Can you try looking at
the disassembly to see if you can find 'm' in one of the registers?
