Subject: ttyS* names missing in /proc/interrupts?
Date: Thu, 12 Mar 2009 14:20:12 +0200 (EET) [thread overview]
Message-ID: <Pine.SOC.4.64.0903121418240.11504@math.ut.ee> (raw)
Just noticed in 2.6.29-rc7+git: lines corresponding to 8250 ttyS*
serial ports have no device name in /proc interrupts:
CPU0
0: 35 XT-PIC-XT timer
1: 338 XT-PIC-XT i8042
2: 0 XT-PIC-XT cascade
3: 3 XT-PIC-XT
4: 3 XT-PIC-XT
6: 5 XT-PIC-XT floppy
7: 1 XT-PIC-XT parport0
8: 2 XT-PIC-XT rtc0
9: 41 XT-PIC-XT acpi, qla2xxx, tr1
10: 1 XT-PIC-XT Intel 82801BA-ICH2
11: 160060 XT-PIC-XT uhci_hcd:usb1, uhci_hcd:usb2, lpfc, tr0, eth0, mga@pci:0000:02:00.0
12: 141 XT-PIC-XT i8042
14: 88730 XT-PIC-XT ata_piix
15: 1190012 XT-PIC-XT ata_piix
NMI: 0 Non-maskable interrupts
LOC: 1028718 Local timer interrupts
TRM: 0 Thermal event interrupts
SPU: 0 Spurious interrupts
ERR: 0
$ dmesg | grep tty
console [tty0] enabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:09: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
And similarly on another machine.
