From mboxrd@z Thu Jan 1 00:00:00 1970 From: Greg Norris Subject: unexpected IO-APIC Date: Tue, 3 Jun 2003 21:19:46 -0500 Sender: linux-smp-owner@vger.kernel.org Message-ID: <20030604021946.GA2246@glitch.localdomain> Mime-Version: 1.0 Content-Type: multipart/mixed; boundary="ZPt4rx8FFjLCG7dd" Return-path: Content-Disposition: inline List-Id: To: linux-smp@vger.kernel.org --ZPt4rx8FFjLCG7dd Content-Type: text/plain; charset=us-ascii Content-Disposition: inline I recently installed Linux on a new i875P-based system, which reports an unexpected IO-APIC during bootup. I don't know what specific information you need, so I've attached the full output from dmesg (kernel version is 2.4.21-rc7). This system experiences prominent problems, reporting lost interrupts under any significant disk (IDE) IO load, when using the IO-APIC. Everything appears to be stable with it disabled. --ZPt4rx8FFjLCG7dd Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="dmesg.out" Linux version 2.4.21-rc7 (root@glitch) (gcc version 3.3 (Debian)) #1 Tue Jun 3 13:16:49 CDT 2003 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 00000000000a0000 (usable) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000003ff74000 (usable) BIOS-e820: 000000003ff74000 - 000000003ff76000 (ACPI NVS) BIOS-e820: 000000003ff76000 - 000000003ff97000 (ACPI data) BIOS-e820: 000000003ff97000 - 0000000040000000 (reserved) BIOS-e820: 00000000fec00000 - 00000000fec10000 (reserved) BIOS-e820: 00000000fecf0000 - 00000000fecf1000 (reserved) BIOS-e820: 00000000fed20000 - 00000000fed90000 (reserved) BIOS-e820: 00000000fee00000 - 00000000fee10000 (reserved) BIOS-e820: 00000000ffb00000 - 0000000100000000 (reserved) 127MB HIGHMEM available. 896MB LOWMEM available. found SMP MP-table at 000fe710 hm, page 000fe000 reserved twice. hm, page 000ff000 reserved twice. hm, page 000f0000 reserved twice.
