I already reported this hangup a while ago but now I get an oops. At that time Gilles said that lapic on old Athlons might be buggy. Does the attached boot log confirm this assumption? 2.6.20-rt8 is working, BTW. Thanks. Wolfgang. --------------000404020906060106020507 Content-Type: text/x-log; name="bernex-ipipe-lockup.log" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="bernex-ipipe-lockup.log" Linux version 2.6.20-ipipe (wolf@domain.hid) (gcc version 4.0.2 20051125 (Red Hat 4.0.2-8)) #1 PREEMPT Sun Feb 25 10:21:36 CET 2007 BIOS-provided physical RAM map: sanitize start sanitize end copy_e820_map() start: 0000000000000000 size: 000000000009fc00 end: 000000000009fc00 type: 1 copy_e820_map() type is E820_RAM copy_e820_map() start: 000000000009fc00 size: 0000000000000400 end: 00000000000a0000 type: 2 copy_e820_map() start: 00000000000f0000 size: 0000000000010000 end: 0000000000100000 type: 2 copy_e820_map() start: 0000000000100000 size: 000000001fef0000 end: 000000001fff0000 type: 1 copy_e820_map() type is E820_RAM copy_e820_map() start: 000000001fff0000 size: 0000000000003000 end: 000000001fff3000 type: 4 copy_e820_map() start: 000000001fff3000 size: 000000000000d000 end: 0000000020000000 type: 3 copy_e820_map() start: 00000000ffff0000 size: 0000000000010000 end: 0000000100000000 type: 2 BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000001fff0000 (usable) BIOS-e820: 000000001fff0000 - 000000001fff3000 (ACPI NVS) BIOS-e820: 000000001fff3000 - 0000000020000000 (ACPI data) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 0MB HIGHMEM available. 511MB LOWMEM available.
