Subject: oops in serial_out in 2.6.5
Date: Tue, 13 Apr 2004 06:37:58 +0000 [thread overview]
Message-ID: <20040413063757.GA11350@hp.com> (raw)
I'm (trying to) run Debian's 2.6.5-mckinley-smp on an hp rx2600. It
oopses at startup in setserial. The console is ttyS0, which points to
the management processor.
Loading the saved-state of the serial devices...
Cannot set serial info: Device or resource busy
/dev/ttyS0 at 0x0000 (irq = 49) is a 16550A
/dev/ttyS1 at 0x0000 (irq = 60) is a 16550A
