Created attachment 116887 [details] dmesg output for a working 2.6.11-1.35_FC3smp kernel
Description of problem: After getting into troubles with 2.6.12-1.1372_FC3smp (it does not work as described in bug 163407 and bug 163437) I tried to boot one of machines with 2.6.12-1.1372_FC3. This did boot, very slowly, but I got flooded with errors like that: ACPI-0686: *** Error: acpi_ev_gpe_dispatch: No handler or method for GPE[20], disabling event ACPI-0686: *** Error: acpi_ev_gpe_dispatch: No handler or method for GPE[21], disabling event ..... and all of this seems to slow down a machine to a crawl. Looking at logs these errors start to be recorded immediately after syslogd is active and they come is a rate about forty per minute. Indices for "GPE" contnuously cycle in 0x20-0x3F range. An output from dmesg was useless because even before /var/log/dmesg was written it was already overrun by error lines like the above. Attached are dmesg output for a working 2.6.11-1.35_FC3smp kernel, an output from dmidecode for the board, an output for 'lspci -tv' and whatever is in /proc/acpi/dsdt. An output from that does not differ between 2.6.11-1.35_FC3smp and 2.6.12-1.1372_FC3 kernels. I am afraid that my access to this machine is somewhat limited and pretty soon for quite a while I will be not able to get to it at all. Version-Release number of selected component (if applicable): 2.6.12-1.1372_FC3
Created attachment 116888 [details] dmidecode data for the board in question
Created attachment 116889 [details] 'lscpi -tv ' output
Created attachment 116890 [details] compressed output from 'cat /proc/acpi/dsdt
I should add that the same 2.6.12-1.1372_FC3 kernel on different boards does not show any acpi problems; but none of other boards where I could try that happens to be SMP.
I booted the machine in question with 2.6.12-1.1376_FC3smp (booting with 2.6.12-1.1372_FC3smp was not ever possible, even with an updated mkinitrd) and so far it does not show any ill-effects. An output from dmesg is very close to the one from 2.6.11-1.35_FC3smp.
ok, closing based on comment #6
